India’s Electronics Boom: Spearheading The Global Market from Import to Export

Weeks after Shri Narendra Damodardas Modi became the Prime Minister of India in May 2014, a meeting has been summoned by the PM in Vigyan Bhawan for discussing key development strategies and the roadmap for India. While discussing the current policies and strategies, the PM also urged for Making products in India. In fact, separate funds and campaigns must be done to boost the industrial sectors in India. After highlighting all the sectors, the PM urged to formulate separate policies and form investment plans to bolster the electronics and semiconductor ecosystem in India. Quoting the impact of growing the electronics industry, the PM said that along with developing other social issues, there is a requirement to grow this sector and make it globally competitive as it has the huge potential to contribute in macroeconomics. This is when full effort and initiatives have been undertaken by the government to grow the industry. In the middle of the digital revolution, there is a requirement for all the nations to grow and boost their electronics manufacturing ecosystem. “Make-in-India”, “Aatmanirbhar Bharat”, and “Vocal for Local” are some the campaigns that elevated the confidence among the indian electronics companies to produce goods locally for domestic consumption and exports. 

Speaking of India's growth in export and production in the ESDM sector, exports of electronic goods reached Rs 41220 crores, and production reached Rs 388306 crore in 2017 as per a report by the government. By 2022, exports reached Rs 109797 crore and production had reached Rs 6,40,810 crore. Speaking of macroeconomics, in the financial year 2022, the contribution of domestic production value of electronics to Indian GDP was about 2.7 percent. This contribution share was estimated to increase to 4.7 percent by the financial year 2026 in the country.

In a very short span of time, the government in association with the industry bodies and the manufacturers has changed the dynamics of the electronics manufacturing ecosystem. It is growing at such a rapid pace, the government has now set a target of $300-$400bn worth of total production by 2026. Have you ever imagined why the entire world is now undertaking efforts to boost this sector? It is event that COVID-19 has spurred the demand of electronics and semiconductors all over the world, but demand has already augmented with the proliferation of the internet and increased pace of digitization. Hardly, there are any industrial sectors that can survive without electronics. From smart home to automobiles, FMCG, and other sectors, electronics have dominated most of the industrial sectors. This industry has the potential to contribute massively to the GDP of a country. 

Policies and Schemes That Redefined India’s Electronics Manufacturing Ecosystem

After several rounds of discussions in regards to growing the industry, the then government and the industry bodies like ELCINA has formulated the first policy in 2012 directed towards growing the electronics industry in India, dubbed National Policy on Electronics (NPE). Under its aegis, Electronics Manufacturing Cluster EMC 1.0 was formed. Although it’s termed as the most comprehensive policy formulation, the NPE 2012 failed to attract big-ticket investments, seed high value-added manufacturing in the India ESDM ecosystem, or create large-scale employment, according to the Economic Times report by Rajoo Goel, Secretary-General of ELCINA. According to R. Swaminathan’s report, NPE 2012, comes on the back of a strong and sustained demand for consumer electronic goods that accounted for a hefty bill of US$125 billion. However, just about 10 percent of India's consumption was produced internally; the rest was imported. 

Can a nation bolster electronics manufacturing at large-scale without developing the components ecosystem? Although the electronics industry is being developed at various fronts, the country still outsources 80 percent of components and raw materials from China and other countries. The industry bodies and the manufacturers have constantly stressed the importance of developing components and the semiconductor ecosystem. After several years of NPE 2012, the government revised the policy in 2019 and under its aegis launched the much-appreciated Production Linked Incentive for 14 sectors worth Rs. 197 lakh crores. 

M-SIPS Investments Table

Under NPE 2019, Modified Special Incentives Scheme (M-SIPS), Electronics Manufacturing Clusters (EMC), and Scheme for Promotion of Manufacturing of Electronic Components and Semiconductors (SPECS) have been announced to boost the industry. In fact, the Aatmanirbhar Bharat campaign initiated during the pandemic in 2020 also played a key role in motivating manufacturers to make products in India and highlighted the imperativeness of self-reliance in electronics manufacturing. This is when Foxconn, Pegatron, and Wistron, now acquired by Tata, started producing Apple’s iPhones in the southern part of India.

The Scheme for Promotion of Manufacturing of Electronic Components and Semiconductors (SPECS) was notified on 1st April 01, 2020. The SPECS Scheme provides financial incentive of 25% on capital expenditure for the identified list of electronic goods that comprise downstream value chain of electronic products, i.e., electronic components, semiconductor / display fabrication units, ATMP units, specialized sub-assemblies and capital goods for manufacture of aforesaid goods. .Over the tenure of SPECS Scheme, the expected new investment in Electronic Components and sub-assemblies was Rs 20,000 crore. The total employment potential of the scheme was approximately 6,00,000 (1,50,000 direct employment and 4,50,000 indirect employment). Under this scheme, around 32 companies have been selected and given incentives. 

Then, in an effort to create a world class infrastructure, the government again revised the original Modified Electronics Manufacturing Clusters in 2020, dubbed EMC 2.0. Under EMC 2.0 scheme, 3 EMC applications covering an area of 1,337 acres have been approved with project cost of Rs 1902.69 crore including financial assistance of Rs 889.02 crore from Government of India. These EMCs are poised to attract an investment of about Rs 20,910 crore and have potential to generate 51,520 employment opportunities after getting operational. An amount of Rs 205.24 crore has been released for scheme execution.

The industry bodies have also stressed for promoting large scale electronics manufacturing. The NDA government amended this scheme twice – in August 2015 and in January 2017, and mainly provided a Capex subsidy of 20-25%. It was closed on 31st December 2018 to receive new applications. In this scheme, 320 applications with proposed investment of Rs 89,194 crore are under consideration. Out of these 320 applications, 315 applications with proposed investment of Rs 86,904 crore and committed incentives of Rs 9,566 crore have been approved. Incentives amounting to Rs 1917.09 crore have been disbursed.

The important point to be noted is that semiconductors form a major part of all electronic products, as a result of growth in the electronics manufacturing sector. This market in India has also witnessed proportionate growth over the last few years. As per the industry estimate, the semiconductor consumption in India was around Rs 1.1 lakh crore in 2020 which is being met through imports due to absence of commercial semiconductor fabs in India. The vision of AtmaNirbharta in electronics & semiconductors was given further momentum by the Union Cabinet chaired by the Hon‟ble Prime Minister approving the Semicon India program with a total outlay of Rs. 76,000 crores for the development of semiconductor and display manufacturing ecosystem in our country. According to minister of electronics and IT for State Rajeev Chandrashekar, India is now looking forward to achieving $56 billion in semiconductors by 2026 and $110 billion by 2030.

The total outlay of India’s semiconductor program has helped the country to witness US based global semiconductor company Micron’s new assembly and test facility in Gujarat, India at an investment of $2.75 billion out of which the company will receive 50 percent fiscal support for the total project cost from the Indian central government and incentives representing 20 percent of the total project cost from the state of Gujarat. Micron’s new facility will enable assembly and test manufacturing for both DRAM and NAND products and address demand from domestic and international markets.

Most importantly, India also witnessed the first semiconductor fabrication unit, a joint collaboration between Tata Electronics and Taiwan’s Powerchip Semiconductor Manufacturing Corp. (PSMC) with an investment of Rs 91,000 Crore. Apart from the fab approval, the cabinet also approved Tata Semiconductor Assembly and Test Pvt. Ltd’s ATMP unit in Assam with an investment of Rs 27,000 crore. Interestingly, Japan’s Renesas Electronics and India’s CG Power have also formed a joint venture to set-up another ATMP unit in Sanand region of Gujarat with an investment of Rs 75,000 crore. Interestingly, home-grown companies such as Sahasra group, Suchi Semicon, and HCL and in association with Foxconn have announced semiconductor OSAT units.

Global Strategies That Will Spurr India’s Growth in Electronics Value Chain

With the onset of COVID-19, anti-China sentiments started growing in India, US, Europe, and in several nations. In fact, the global companies such as Foxconn, Intel, Samsung, and others started finding alternatives other than China to set-up their production units. Apart from Vietnam and Philippines, India is the most preferred destination among the global companies.

Geopolitically speaking, ChinaPlus One Strategy is already helping India to grow its ESDM sector in various ways and the alliance with the USA will give India further impetus to boost its semiconductor industry both in terms of investment and revenues. The major problem is China is still leading the component industry and without that you can grow your industry. Therefore, both India and the US must find solutions to grow its component sector. Global investments have already happened in India and experts assure the close association with the US will make India a major player in the ESDM sector internationally.

As no one would like to put eggs in one basket. India has an added advantage in terms of design experts as leading semiconductor companies have design houses here and It's the manufacturing and IP where we catch up and we believe India is at the right place at the right time. Semi content within categories is increasing, while the electronic devices growth will continue too. Promoting product design, including both hardware and software can be a first step in making India a hub for the electronics system design and manufacturing sector. India semiconductor market consumption is all set to reach $64Bn by 2026 with a CAGR of 16 percent.

According to Mr. Rajoo Goel, India now stands out as a bright spot and beacon of hope.  With our focus on the ESDM sector, India has been pulling out all stops for enabling the electronics eco-system and establishing itself as a serious player in the global industry.  While our economy and markets are growing, demand growth outpaced supply and we remained dependent on growing imports. Concerted efforts in the last few years have salvaged the situation somewhat. However, much more needs to be done to create a sustainable ecosystem especially with respect to value addition and manufacturing of components.

"In this situation the India Taiwan partnership has great potential, particularly because we are aligned by our values of being trusted Partners and more importantly, our strengths and weaknesses complement each other. This presents a great opportunity for success through collaboration. Taiwan is looking to strengthen its partnerships in all domains with India, especially in the electronics and ICT domain.  The gravitas with respect to India is growing with our steadily growing economy from 5th position currently to the expected 3rd rank by the end of this decade. All our trusted Partners and most of the world are looking towards the economic success of India with the conviction that India would be a stabilizing factor in the current fractured world and be a strong player in the global value chain,” added Mr. Goel.

Of late, various reforms and policy measures have been announced with an aim of escalating the share of manufacturing in gross value added (GVA) to 25 percent. In the financial year of 2019-20, the manufacturing cluster offered 17.1 percent of GVA and exports accounted for 20.7 percent of the overall manufacturing yield. The point to be noted is that none of the computer chips are completely manufactured in India yet and although US semiconductor firms have shown a lot of optimism to India there is still a discrepancy between what has been committed in eloquence and what has been assured in a signed document.

India’s Electronics Manufacturing Boom: From Import to Export

According to research body IBEF, overall, electronics manufacturing saw exponential growth to reach US$ 67.3 billion in 2020-21 from US$ 37.1 billion in 2015-16. However, the COVID-19 pandemic caused serious disruptions across the globe, but the industry has shown strong signs of recovery. India has been one of the pioneers of the Local Goes Global movement. The country is focusing on developing its share in the global value chain, establishing export hubs in different states, constructing a high-quality and seamless supply chain, and increasing its overall market share in the electronics export market. The Digital India Program has led to a paradigm transition towards digitization and e-governance in India. India's market share in the global electronics manufacturing industry increased to 3.6 percent in 2020 from 1.3 percent in 2012. 

A US$ 1 trillion digital economy target is projected to boost demand for electronics, which may stand at around US$ 180 billion by 2025-26. If India can accomplish the manufacturing goal of US$ 300 billion for electronics, the local market requirement may be fully met by such manufacturing. The US$ 300 billion target also requires US$ 120 billions of exports in the global market. 

Speaking about the growth of India’s EMS sector, Vinod Sharma, managing director, Deki Electronics, said, “India’s electronics manufacturing ecosystem is certainly growing very rapidly, but most importantly, the industry today believes that it has the potential to grow globally. India is now becoming a favored destination for electronics manufacturing.  For instance, the PLIs for IT hardware, mobile phones, LED’s, and consumer electronics have mostly sparked the assembly department. It incentivizes locally made components, but in the last ten years, we have become a huge assembler and exporter at the same time. We are expecting that there will be some sort of incentives given by the government in component manufacturing. Although PLI is the most game-changing policy of all, it should reach the smaller companies and target the component sector. It mostly attracted the larger companies because the investment ratios are very high.”

India is one of the largest mobile handset manufacturing countries globally and the second-largest smartphone market in the world. The Ministry of Electronics and Information Technology (MeitY) unveiled the Phased Manufacturing Programme (PMP) for cellular handsets and other sub-assemblies with an aim to scale up domestic value addition. Manufacturing of mobile phones rose to 290 million units in 2020-21 from 60 million units in 2014-15. Mobile phone exports from India will grow more than fivefold to USD 50-60 billion in the coming time from about USD 11 billion last year, Union IT and Communications Minister Ashwini Vaishnaw said. He said that 10 years ago India imported 98 per cent of mobile phones and at present 99 per cent of the devices are made in India. Around 10 lakh people work in electronics manufacturing. In the coming days, 25 lakh people will work in electronics manufacturing. The minister also added that India will become the third largest economy by 2027 while it was ranked 11th in 2014.

Now, when it comes to the Information and Communication Technology (ICT) Hardware, the first use of electronics was in the communication and computing domain. In 2020, India witnessed a surge in ICT hardware demand due to COVID-19-led disruptions. Due to the remote working trend, households and individual customers purchased tablets and computers. Enterprises have heavily spent on their data center infrastructure (to ensure steady demand amid work-from-home and online dealings), and telecommunication service providers have been modernizing their infrastructure to cater to surging broadband demand.

Ten out of the 40 companies that applied for the Centre's revised production-linked incentive scheme for IT hardware have started production from 1 July 2023, while 25 plan to begin manufacturing by 1 April 2024, according to MeitY. The government expects an incremental investment of Rs 5,010 crore from the 40 applicants, including global IT hardware companies such as Dell and HP that are participating directly under the revised production-linked incentive scheme. Other major players such as HPE, Lenovo, Acer, ASUS, Thomson were participating through electronics manufacturing services providers or contract manufacturers including Flextronics and Rising Stars, a unit of Foxconn Technology Group in India. Officials added that Indian companies such as Padget, a subsidiary of Dixon Technologies, VVDN, Netweb, Syrma, Optiemus Technologies, Sahasra, Neolync, Panache, Sojo, a unit of Lava mobiles, and Kaynes have also participated in the scheme which will get impetus from the strong IT services industry which was driving the demand within the country.

Consumer electronics is another key domain whose manufacturing and demand has escalated tremendously in the country over the years. According to the Federation of Indian Chambers of Commerce & Industry (FICCI), India's television production was US$ 4.24 billion in 2020-21 and is anticipated to reach US$ 10.22 billion by 2025-26, expanding at a Compounded Annual Growth Rate (CAGR) of 20%. The kind of television sets available in the market includes a wide variety of LCDs, plasma, LEDs and so on, offering high resolution and sharp picture quality. Additionally, a decreasing trend in the pricing of LED and LCD televisions is fuelling the penetration of such televisions in the market. A few initiatives taken by the government include increasing the basic customs duty on multiple consumer electronics goods in order to push companies into replacing imported goods. Furthermore, the government has permitted 100% Foreign Direct Investment (FDI) in the consumer electronics manufacturing segment through the direct route and offered capital expenditure subsidy under the Modified Special Incentive Package Scheme (M-SIPS). 

Electronics Production in India

The ELCINA CTF report also highlighted that the industry’s ecosystem has evolved to keep pace with the changing demand patterns. The supply chains are now far more complex, diverse, and optimized to meet the new industry structure. Currently, a significant share of Indian demand is met by imports. But the Indian electronics industry is being ushered into an era wherein the manufacture of several components will be indigenized through regulatory support and incentivized production from the government of India. There have been several policies such as Make in India, National Policy of Electronics 2019, Production Linked Incentives (PLI) & Phased Manufacturing Program (PMP) etc. which are primarily to promote domestic manufacturing, lowering import dependence, and expanding exports.

The electronics industry in India has been one of the fastest growing sectors. It has grown at a healthy pace of 15% over the last 7 years, despite Covid as shown in the Chart below. The Indian Electronics manufacturing has reached Rs 625,950 Crores in 2021-225 comprises of  Mobile Phones (44%), Industrial Electronics (16%), Consumer Electronics (14%), Electronic components (13%), Strategic Electronics (6%), Computer Hardware (4%) and LEDs (3%).

Highlighting further on India’s potential to grow the industry, Amrit Manwani, managing director Sahasra Group, said, “The industry has seen sea change towards policy for this sector. In the last tens years, the electronics industry has seen a proper direction that has helped to expand its presence in the global market. All the three PLIs which have been announced in the last three years including the SPECS scheme have boosted investments in the sector. But as far as PLI for IT hardware 2.0 is concerned, this should actually stimulate the manufacturing of IT hardware products in India, which has witnessed a very nominal growth in the last seven decades. In the coming five to six years, this scheme will pose a significant growth in electronics manufacturing. It will not only make us self-reliant, but will also address various security concerns through the import of the IT hardware products.”

Growth of India’s Electronic Components Market-Overview

Although India has set to achieve a target of $300 billions of electronics by the end 2025, industry leaders feel that the country’s component manufacturing is still in its nascent stage. According to Viond Sharma, managing director of Deki Electronics, in the current product mix, out of the 100 billion dollars, we are actually manufacturing 52.7 percent of the electronics components, according to last year's data. Around 150 billion dollars of components will be required to reach the target.

The global market for electronic components is expected to reach USD 2,628 billion in 2022, of which the Asia Pacific region is going to capture a dominant share. Following this global trend, the Indian electronic components market is also poised to grow significantly. This growth will be driven by rising local demand and growing disposable incomes. Apart from this, the adoption of high-end technology devices, technology-driven transformation such as the roll-out of 5G/4G/LTE networks and the Internet of Things (IoT), policy and incentive boosts from the government like ‘Digital India’ and ‘Smart Cities’, wider broadband connectivity, e-governance programmes, etc, are all driving the accelerated adoption of electronic products.

The growth of the electronic products industry has started driving the expansion of the electronic components industry as well. According to ELCINA, the market size of the Indian Electronic Components Market in India [(Domestic Production – Exports) +Imports] increased from USD 11 billion in FY 2009-10 to USD 29.9 billion in FY 2021-22 (excluding the Imported PCB-Assemblies), with a year-on-year growth rate of around 8.7 percent. The Electronic Components Market has largely grown driven by a huge increase in Mobile Phones manufacturing in India in the last 2 years. The Electronic Components Market in India including Imported PCB-Assemblies is estimated to be around USD 39.2 billion.

Mobile Phones, Consumer Electronics and Industrial Electronics account for the major demand (85%) for electronic components in India. This is followed by Computer Hardware, strategic electronics and lighting industry contributing to the balance of the market. The Indian Electronic Components Market seems to be largely dependent on imports which accounts for over 68 percent of the Indian Market requirement. Nearly 37% of the local production of Electronic Components is exported. Industries like Mobile Phones, Industrial Electronics (due to the advent of EVs) and Strategic Electronics are expected to witness substantial growth in the near future. The Indian Electronic Components Market (Excluding Imported PCB-Assemblies) was estimated to be around USD 27.3 billion in FY 2021-22 as shown below in Chart below.

GaN HEMTs: Future Power Semiconductors

Submitted by Staff on

Silicon-based metal oxide semiconductor field effect transistors (MOSFETs) have been the standard in power electronics applications since the 1960s. Still, the evolution of various technologies—particularly in the automotive and consumer electronics sectors—have created new challenges for developers seeking to provide higher efficiency and greater power density in increasingly smaller form factors. Power supplies for everything from large data centers and wall outlet AC adapters to onboard charging stations in automobiles require high voltages while taking up as little valuable board space as possible. Self-driving cars also require more efficient energy distribution to operate the growing number of imaging devices and sensors used to navigate and detect potential obstacles. And while silicon-based semiconductors have essentially already been maxed out in higher-demand implementations, GaN-based (gallium nitride) semiconductors are increasingly proving to be an optimal solution for these types of design challenges.

Understanding GaN HEMTs

GaN HEMTs (High Electron Mobility Transistors) aren’t necessarily a better option than Si MOSFETs, silicon carbide (SiC) MOSFETs, or IGBTs (insulated-gate bipolar transistors) in every design scenario. However, they are particularly well-suited for applications requiring high-frequency performance in the medium voltage range. 600V GaN FETs are most commonly used in traditional power supplies for everything from personal computers and consumer electronic devices to base station power supplies and wireless charging devices. In contrast, SiC MOSFETs can provide up to 1200V, making them a better fit for applications with higher current requirements like automotive traction inverters and large-scale solar farms. Despite providing less power than SiC MOSFETs, GaN HEMTs operate at higher frequencies—greater than 200kHz—delivering faster switching speeds with reduced transmission loss. And although GaN HEMTs feature a power density similar to traditional Si MOSFETs, their capacity to operate at higher frequencies makes them ideal for wireless charging applications. SiC MOSFETs and IGBTs are better suited for sets that require more power but less efficiency (i.e., electrically powered vehicles, large industrial machinery) or enormous power consumers like server farms.

What ‘s more, GaN HEMTs are offered in smaller form factors than conventional MOSFETs while being less costly to manufacture and operate. The raw materials used in GaN technology are also significantly less expensive than those in SiC devices. For example, GaN requires less heat than SiC to produce, resulting in significant energy savings for manufacturers. Additionally, GaN devices are developed on silicon substrates, as are most integrated circuits, allowing developers to use pre-existing production methods and facilities to produce GaN HEMTs with very little retrofitting. Finally, post-production operation of GaN HEMTs consumes less power and requires less cooling and, therefore, less energy to operate than SiC MOSFETs, providing additional cost savings to the consumer. 

One drawback of GaN HEMTs is the need to be used in conjunction with gate drivers in certain implementations due to their narrow optimal drive voltage. If the drive voltage is too low—less than two volts—the device may malfunction and turn on by itself, and if the gate withstand voltage is too low, the gate itself might break down. The optimal drive voltage for GaN implementation is between 4.5V and 6V—any less may mean it won't turn on, and any more might fry the circuit. Incorporating an external gate driver helps maximize transistor performance but takes up additional space on the board, which is a factor developers must consider. However, GaN devices produce less heat and require less cooling than their silicon-based counterparts, potentially lowering energy and maintenance costs for the customer even further.

The many benefits of using discrete GaN HEMTs may seem to be significantly restricted by the issues described above, but overcoming these limitations is possible. One advantage of GaN HEMTs is that they can be built on the same substrate as other integrated circuits, enabling additional circuitry to be included in the same device. For example, circuits for controlling the drive voltage to within the desired range to prevent a low voltage from turning on the device unexpectedly or driving the gate voltage too high and potentially damaging the device. At the same time, an integrated solution typically costs less than a discrete configuration, takes up less board space, reduces parasitic effects, and simplifies board layout. And from a performance standpoint, an integrated solution can maintain and even improve the high operating frequency advantage of the GaN HEMT compared to a multiple-device implementation. Reliability is also increased—a benefit that is very important for many power delivery applications.

ROHM Semiconductor’s Nano Cap™ 650V GaN HEMT Power Stage ICs combine the high-power density and efficiency of GaN technology with a silicon driver to form a fully integrated IC solution. GaN ICs are not only an optimal fit for medium voltage applications like base station chargers and power adapters—they can be implemented in industrial applications and high-density power supplies as well. The lower cooling requirements of ROHM’s GaN ICs minimize the need for heat sinks and other cooling mechanisms, further reducing physical board space. In fact, it wouldn’t be surprising to see GaN’s smaller form factor (and superior efficiency) eventually overtake silicon-based ICs as technologies continue to evolve, especially when implemented in tandem with gate drivers. For mobile applications that require ultra-high frequency operation and loss minimization, ROHM’s Nano Cap 650V GaN HEMT Power Stage ICs provide a complete and efficient solution.

Conclusion

Gallium Nitride HEMTs represent a promising frontier in power semiconductor technology, offering efficiency improvements and cost advantages for various applications, from consumer electronics to power delivery systems. With ongoing advancements and integration possibilities, GaN HEMTs, like those from ROHM Semiconductor, are poised to reshape the landscape of power electronics.

Storage Temperature TSTG -65   150 °C
Lead Temperature During Soldering - - - 265 °C

Firstly, take note of the Operating Voltage. This IC can operate with a minimum voltage of 3V and a maximum of 20V. However, for optimal stability in terms of power dissipation and oscillating frequencies, recommended operating voltages are 5V, 10V, and 15V. Regarding Current Consumption, since this IC is designed for low-power operation, it typically ranges from 2µA to a maximum of 200µA.

Next, let's consider Input and Output Voltages, which depend on VDD and VCC. For instance, with a supply voltage of 5V, a voltage below 0.5V is considered LOGIC LOW, while a voltage between 0.5V and 4.5V (or up to VDD) is considered LOGIC HIGH.

Unlike some other ICs, this IC is available in various variants with different Operating Temperatures to suit specific needs. Choose the variant that best fits your requirements. The top variant operates at a temperature of around 125°C. When soldering, be cautious not to overheat the IC's leads beyond 265°C to prevent internal damage. For more detailed information, refer to the official datasheets available online.

CD4047 - Operating Modes 

The CD4047 primarily offers two main functions: Astable Multivibrator and Monostable Multivibrator. Within these functions, there are 3 modes for Astable operation and 4 modes for Monostable operation as shown in the image below:

Operating Modes in CD4047 IC

You might be wondering about how to switch between these modes. Don’t panic—switching between these modes is made simple using the table below

  TERMINAL CONNECTIONS TERMINAL CONNECTIONS TERMINAL CONNECTIONS

External Countdown 14 5, 6, 7, 8, 9, 12 - 10, 11

By following the terminal connection table provided above, you can easily set the respective modes. The external capacitor and resistor pins remain the same for every mode; only their values might change according to specific needs.

Regarding the outputs, there are three pins: Q, Q̅ (Q-bar), and Oscillator Out. Q is the main output, Q̅ is the complement output of Q, and Oscillator Out is a direct output from the Astable Multivibrator block of the IC. The Q and Q̅ outputs come from the frequency divider block, which divides the frequency by two.

Let's delve into the modes of operation of the CD4047 starting with the Astable Multivibrator mode. Among the available three modes (Astable, Monostable, and Bistable), we will begin with a detailed explanation of the Astable Multivibrator mode. We'll cover Free Running mode briefly and discuss its stimulation.

Following that, we'll explore the Monostable Multivibrator mode, which offers four distinct modes. In particular, we will focus more on the Positive Edge Trigger mode within the Monostable Multivibrator configuration, providing a deeper understanding of its operation and applications.

CD4047 as an Astable Multivibrator

In simple terms, an Astable Multivibrator is a circuit that generates a continuous output oscillating between two states, typically producing a square wave (Q) as shown in the figure below.

Astable Mode Output waveform of CD4047

This square wave finds numerous applications in digital electronics. The below gifs shows the CD4047 working in Astable mode, we have used an LED to provide a visible Output of the generated continuous square wave. You can notice that the LED turns on when the square wave is high and tuens off when the wave is low. Here the Q was the Square wave Generated by the 10th Pin and that's Where the LED is Connected. OSC is the Oscillator Output, which was not used in the above setup.

As previously mentioned, the CD4047 offers 3 modes within astable operation. Lets discuss each mode separately in details 

Free Running Mode of Astable Multivibrator

In Free Running Mode, a series of square waves is continuously generated whenever the system is powered up. In this mode, we can adjust the frequency of the oscillated output while the circuit operates autonomously. 

Circuit Diagram for Free Running Mode of CD4047

The above circuit diagram depicts the Free Running Mode configuration of the CD4047 IC. Here's a breakdown of the connections:

  • Pins 4, 5, 6, and 14 are connected to the positive supply voltage (+5V).
  • Pins 7, 8, 9, and 12 are connected to the negative supply voltage (Ground/Gnd).
  • A 10uF capacitor is connected between Pins 1 and 3.
  • A 22KΩ resistor is connected between Pins 2 and 3.
  • An LED is connected to the 10th Pin (Q) along with a current-limiting resistor of 220Ω.

For simulation purposes, an oscilloscope is connected to Pins 10 (Q output), 11 (Q̅ output), and 13 (OSC output) to observe the waveform outputs and timing characteristics of the CD4047 in Free Running Mode. This setup allows for visualizing the oscillation behavior and waveform generation of the circuit.

Graph Representing IO States in Free Running Mode of CD4047

Calculation of Pulse Width for Astable Multivibrator

This part of the calculation Remains the same for All the Modes in the Astable Multivibrator

The timing (tA) is calculated using the formula:
        tA = 4.40 x R x C

For example, using a chosen capacitor of 10µF and a resistor of 22KΩ:
  tA = 4.40 x 22K x 10µF
      = 0.968 sec

So, approximately, it can be considered as 1 second. Remember, tA represents the timing of the full cycle. To determine the half-cycle time, simply divide tA by two.

The ideal waveform was provided above, for your reference. There is no Trigger Signal, as powering up the circuit itself Starts the oscillator. Here Q was the actual output, and Q̅ was the Inverted Output. OSC was the internal Astable oscillator’s direct output. So, Technically the Q and Q̅ was the output from the internal frequency divider which divides the frequency by two. These square waves are generated continuously with the predefined frequency with the help of R and C.

Stimulation of Free Running Astable Multivibrator:

As per the circuit diagram of Free Running mode explained above, the circuit was replicated in the Proteus for Stimulating the CD4047 in Free Running Astable Multivibrator Mode. 

Free Running Mode Stimulation Output of CD4047

The above was the simulation result of a free-running astable multivibrator. Here, the expected pulse interval was calculated as tA = 4.40 × 10 µF × 22 kΩ = 0.968 seconds. However, in the simulation above, we obtained a result closer to 1.1 seconds, which was quite acceptable. We also created a prototype on a breadboard and achieved the expected result. 

However, it's important to note that in the real world, there are many factors that can affect timing. Therefore, fine-tuning your circuit to achieve a precise frequency can be quite challenging!

True Gating mode in Astable Multivibrator

As Like in the free running mode, a series of square waves are generated, but with the condition that it requires a trigger signal. 

Circuit Diagram for True Gating Mode of CD4047

The above circuit diagram of the True Gating Mode configuration of the CD4047 IC. Here's a breakdown of the connections:

  • Pins 4, 6, and 14 are connected to the positive supply voltage (+5V).
  • Pins 7, 8, 9, and 12 are connected to the negative supply voltage (Ground/Gnd).
  • A 10uF capacitor is connected between Pins 1 and 3.
  • A 22KΩ resistor is connected between Pins 2 and 3.
  • An LED is connected to the 10th Pin (Q) along with a current-limiting resistor of 220Ω.
  • The 5th pin (ASTABLE) is intended to be an input here. It is connected to 5V via a push button and pulled down via a 10KΩ resistor.

Graph Representing IO States in True Gating Mode of CD4047

The square waves are produced only when the Trigger pin is kept HIGH. If the Trigger pin is LOW, the oscillator remains turned OFF. You can see this in the above Ideal Graph. Here if the pulse width of the Trigger input was low than tA, Output will be held ON for the first cycle of Oscillations as Shown above.

Complement Gating - Astable Multivibrator

Complement Gating is similar to True Gating, as the name implies. In Complement Gating, the oscillator is turned on by an active LOW signal and turned off by an active HIGH signal. To achieve this operation, a slight change in the circuit connection is required.

Circuit Diagram for Complement Gating Mode of CD4047

The circuit was actually the same as the true astable gating, but with only one difference. Here, the 4th pin ( A͞S͞T͞A͞B͞L͞E͞ ) served as the trigger input. This pin was connected to ground via a push button and pulled up via a 10 kΩ resistor. So, the 5th Pin along with the Pins 8, 9, 12 was Connected to Negative Power Supply (GND or Ground)

Graph Representing IO States in Complement Gating Mode of CD4047

Like the circuit, the above ideal graph was very similar with only one difference: the trigger signal appears inverted.
So with this, we are completing the Astable Multivibrator modes. Next, let's explore the Monostable Multivibrator and its modes.

Monostable Multivibrator

As the name implies, the Monostable function has only one stable state, which changes to an unstable state when an external trigger is applied. After a fixed period of time, it returns to the original stable state. This functionality is commonly used as a timer in various applications. While modern microcontrollers are more capable than this simple IC, the CD4047 excels in speed, efficiency, reliability, and cost for specific tasks.

The following GIF demonstrates the CD4047 operating in Monostable Multivibrator Mode. In this setup, a push button is used to trigger the timer, and an LED is used to indicate the output visually.

Below is a graph representing the basic output waveforms of the Monostable Multivibrator. The TRIG waveform is generated when pressing the push button, and the Q waveform represents the output from the 10th Pin (Q), where the LED is connected.

Positive Edge Trigger mode Output waveform of CD4047

Next, let's begin with an introduction to the calculation part of the Monostable Multivibrator.

Calculation of Pulse Width for Monostable Multivibrator

This part of the calculation remains the same for all modes in the Monostable Multivibrator.

The timing (tM) is calculated using the formula:
        tM = 2.48 x R x C

For example, using a chosen capacitor of 1000µF and a resistor of 400Ω:
  tM = 2.48 x 400 x 1000µF
      = 0.992 sec
So, approximately, it can be considered as 1 second. 

Now, let's delve into the operating modes of Monostable Multivibrator, Starting from the Positive Edge Trigger Mode.

Positive Edge Trigger - Monostable Multivibrator

The Positive Edge Trigger is simpler to understand in its basic operation as a timer. When the trigger push button is pressed, the output is held high for a specific amount of time and then pulled low. This is the primary application of this configuration.

Circuit Diagram for Positive Edge Trigger Mode of CD4047

The above circuit diagram depicts the Positive Edge Trigger Mode configuration of the CD4047 IC. Here's a breakdown of the connections:

  • Pins 4 and 14 are connected to the positive supply voltage (+5V).
  • Pins 5, 6, 7, 9, and 12 are connected to the negative supply voltage (Ground/Gnd).
  • A 1000uF capacitor is connected between Pins 1 and 3.
  • A 400Ω resistor is connected between Pins 2 and 3.
  • An LED is connected to the 10th Pin (Q) along with a current-limiting resistor of 220Ω.
  • Pin 8 (+TRIGGER) was Connected to Positive Supply voltage Via PushButton and Pulled Down Via 10kΩ

For simulation purposes, an oscilloscope is connected to Pins 8 (+TRIGGER), 10 (Q output), 11 (Q̅ output), and 13 (OSC output) to observe the waveform outputs and timing characteristics of the CD4047 in Positive Edge Trigger Mode.

Graph Representing IO States in Positive Edge Trigger Mode of CD4047

While the resulting waveform may resemble that of a true gating astable multivibrator, the key distinction lies in the trigger mechanism. In a monostable multivibrator, if the trigger is pressed continuously for an extended interval, the output is driven high for a fixed duration and then automatically turned off. Conversely, in true gating mode, the output remains continuously high as long as the trigger input is maintained in a high state. 
Here the Trigger pulse is responsible for Switching ON and OFF the Internal Oscillator.

Stimulation of the Positive Edge Trigger in Monostable Multivibrator:

The circuit diagram for the Positive Edge Trigger mode was replicated in Proteus for simulation. As you know, a push button connected to the 8th pin of the CD4047 served as the trigger input, and an LED connected to the 10th pin (Q) of the CD4047 was used as the output indicator. One important thing to remember is that if you want to visually observe the output via the LED, ensure that the calculated pulse width is at least greater than 300 ms; otherwise, it will be too fast to notice.

Positive Edge Trigger Stimulation

The above was the simulation of a Positive Edge Trigger Monostable Multivibrator. We also created a prototype on a breadboard and achieved the expected result.

Please note that there will be slight differences between simulation and real-world prototypes due to factors such as component tolerances. Therefore, you may need an oscilloscope or frequency measuring device to fine-tune the output pulse width. Use potentiometers instead of fixed resistors for easier tuning. Once tuning is completed, you can replace the potentiometer with a static resistor by measuring the actual resistance in the potentiometer.

Negative Edge Trigger Mode in Monostable Multivibrator

It is similar to the positive edge trigger, but in this case, the system is activated by an active LOW signal, which initiates a delay in the circuit.

Circuit Diagram for Negative Edge Trigger Mode of CD4047

To enable Negative Edge Trigger Mode, connect the trigger input to the 6th Pin (-Trigger) with a pull-up configuration, and connect the 8th Pin (+TRIGGER) to the positive supply voltage (5V). The rest of the circuit remains the same as in the Positive Edge Trigger Mode.

Graph Representing IO States in Negative Edge Trigger Mode of CD4047

This graph was similar to Positive Edge Trigger mode as the functions are essentially the same except for the inverted trigger input. You may notice that there was only one rising edge in the oscillator output because after one cycle, the internal astable oscillator was turned off.

Retriggerable Mode in Monostable Multivibrator

This mode is particularly special because it can be utilized to extend the duration of the output pulse. Additionally, it can be employed to compare the frequency of an input signal with that of the internal oscillator.

Circuit Diagram for Retriggerable Mode of CD4047

In this setup, the connection is similar to a positive edge trigger with one modification: the 12th Pin (RETRIGGER) is combined with the 8th Pin (+TRIGGER), meaning both pins receive the same input pulse simultaneously. Therefore, there is no need for individual pull-down resistors. A common pull-down and a common Push Button input are sufficient.

Graph Representing IO States in Retriggerable Mode of CD4047

The above graph depicts the ideal behavior for the Retriggerable Mode. In this mode, there is a feature that allows increasing the pulse width by using multiple trigger pulses. From the graph, it's evident that if the push button is pressed once, the pulse interval is 1tRE. If pressed twice, it's 2tRE, and so on. With continuous pressing, the output pulse will remain on indefinitely.

Unlike others, the Retriggerable Mode has a separate calculation which will be discussed below.

Calculation of Pulse Width Of Retriggerable Mode:

Actually, it is the same as the main formula tM = 2.48 x R x C, with slight modifications due to the introduction of a new variable n representing the number of input pulses.

So, the time delay of a retriggerable monostable multivibrator (tRE) can be defined as follows:

tRE = (2.48 x R x C) x n

For example, using a chosen capacitor of 1000µF and a resistor of 400Ω and considering two pulse input,

tRE = (2.48 x 400 x 1000µF) x 2
       = 1.984 sec
So, approximately, it can be considered as 2 seconds. 

External CounterMode in Monostable Multivibrator

This mode is considered to be an additional feature that requires an external IC to serve as the trigger input signal. It is somewhat similar to the Retriggerable mode, but instead of using a simple push button, an external digital signal is utilized.

Reference Circuit Diagram for External Counter Mode of CD4047

The External Counter option enables extending the time duration of the output pulse beyond the intrinsic limits of the CD4047. By utilizing an additional counter IC in combination with the CD4047, precise digital control over the output pulse duration can be achieved. This method enhances flexibility and accuracy in pulse timing applications.

Due to its unique ability, it has a distinct calculation method which will be discussed below.

Calculation of Pulse Width of External Counter:

Here the formula for calculating the pulse duration (tEC) looks like this,
                tEC= (N - 1) (tA) + (tM + tA/2)  
        Where,
            tEC - Pulse width of External Counter Mode
            N - Number of Counts Set by the External Counter Circuitry
            tA - Time Period of Internal Oscillator
            tM– Desired time period

(N-1) x tA -> Represent the total time taken for N cycles of the internal oscillator.
(tM + tA /2) -> Represents the additional time extended by the external circuitry            

Finally, let's move on to our last topic, which covers limitations of timing components including the range of values for R (resistors) and C (capacitors) that can be utilized, and more.

Timing Component Limitations

  • It is recommended to use non-polarized capacitors with low leakage for optimal performance with the CD4047.
  • There are no strict upper or lower limits for either the resistance (R) or capacitance (C) values to maintain oscillation.
  • Based on internal calculations and practical considerations, the recommended values for R and C are as follows:

Capacitance (C):

  • For astable modes: From 100 pF to any practical value.
  • For monostable modes: From 1000 pF to any practical value.

Resistance (R):

  • Minimum value: 10 kΩ

4th Electronics Supply Chain Summit: Experts Highlights The Opportunities to Grow Security Products Industry in India

  • Various ministries and associated departments were urged via PPO that security and added products will not be purchased from brands that are having a long history of security breaches and data leakage.
  • The global CCTV market is around 2 lakh crores, growing at a rate of 17 percent and is expected to reach more than 100 billion dollars.
  • In the surveillance industry, India has the potential to become the second largest market in the world by 2030

Over the past few years, the world has witnessed a surge in demand for video surveillance and smart security cameras. Although USA and China still grab the top spot of market share in this industry, experts opine that India has the potential to become the second largest market by 2030. CCTV cameras have become an important part of our lives revolutionizing the way we monitor and secure our surroundings. According to a report by Sparsh CCTV, the roots of CCTV cameras can be traced back to the 1940s when German engineer Walter Bruch developed a rudimentary system for monitoring V-2 rockets. However, it was during the 1960s that CCTV technology truly began to flourish. Early systems utilized analog signals, transmitting footage over coaxial cables to limited monitors in control rooms.

Now, with the advancement of technology and rapid increase of crimes, these devices have gained a huge traction all over the world. India's Electronic Security Market was valued at USD 1.32 billion in 2021 and is expected to reach USD 4.90 billion by 2027, at a CAGR of 24.37 percent over the forecast period. The security products industry is growing rapidly and is estimated to escalate by 22 percent per annum, which will sustain by 2025 and beyond. India is emerging as a global power and security is emerging as a priority. We need to ensure India must grow by itself and must be a source of prosperity for the rest of the world. The size of the global security electronics market is intense and valued at US $41 billion in 2020 and is expected to reach US $68 billion by 2026 at a CAGR of 9 percent from 2021-2026.

In an effort to bolster the growth of CCTV and surveillance market in India, the government of India in a recently issued advisory has highlighted the danger of data leakage through CCTVs. Various ministries and associated departments were urged through this advisory that security and added products will not be purchased from brands that are having a long history of security breaches and data leakage. The advisory has been issued by the Ministry of Electronics and Information Technology (MeitY), which has requested all its departments to strictly abide by the guidelines of Public Procurement Order (PPO), which was unleashed on March 6, 2024. 

CCTV Cameras

Recently, in the “4th Electronics Supply Chain Summit” organized by industry body ELCINA, key CCTV manufacturers, government officials and defense personnel discussed the key strategies to boost the surveillance industry and also the emerging opportunities for security products industry in heightened risk scenarios. In the detailed discussion, let’s find out country’ surveillance electronics industry has grown over the years and how its growth will be boosted in the global value chain.

Atul Lal, CEO, Dixon Technologies and President at ELCINA

The global CCTV surveillance industry is going through a significant transformation, which is like a renaissance. The positive impact in this industry is happening because of a huge technological change and there is a vast security challenge globally as well as in India. There is a significant intervention by the government mostly in the policy framework and also huge initiatives have been undertaken to grow Make-in-India. The global CCTV market is around 2 lakh crores, growing at a rate of 17 percent and is expected to reach more than 100 billion dollars. 

The domestic market is growing but it’s most dependent on other countries for crucial electronic components, but it is expected to touch almost 10 billion dollars in the coming years at a CAGR of around 20 percent. This kind of wide adoption of CCTVs has happened because of rapid urbanization, smart city projects, development of various transportation sectors as well as roadways. Crime rates have been increasing. For instance, in Delhi in the month of February, around 4 lakh cases have been registered. The honorable supreme court intervened and strictly instructed all the police stations to have top-notch video surveillance systems. More than 10,000 CCTVs have been installed in the police stations in Bihar alone. The industry is in a very high growth phase. What is extremely important is that MeitY has seriously unleashed the policies like the PPO of 6th of March clearly, which clearly states that preference will be given to the Indian solutions. The initial shift might be tightly slow, but the penetration rate will be high and there will be more Indian solutions involved. In the PPO order it is stated that the CCTV cameras and the related products and equipment will be certified by MeitY. 

Conference Meet

Sanjeev Sehgal, managing director, Sparsh (Samriddhi Automations Pvt. Ltd.)

The Indian government has come up very intelligently with all the policies and frameworks to boost the CCTV security industry in the country. The policy has been created in such a manner that we are able to restrict data leakage and security breach. The government has truly taken a giant leap in this sector. The PPO, which was announced on 6th of March, is going to secure and grow every security equipment, not only CCTVs. You have to manufacture and produce products domestically or else you cannot get any benefits out of this policy. It covers cybersecurity sector as well. Whether it’s a private or government agency, everyone is worried about data security. The video surveillance equipments are now part and parcel of our lives. If the Indian domestic industry benefits from this policy and aligns themselves with the vision of the government and MeitY, there is definitely a big way forward for the industry not only for India but also for the world. India has the opportunity to become a CCTV factory for the world. The industry is fully committed to design products in India and fulfill the vision of the government. 

Aditya Khemka, managing director of CP PLUS

First of all I must say that associations like ELCINA is doing a great job in bringing the manufacturers and the government together because unless all the stakeholders work together there is no possibility to grow the industry. Now speaking of the industry, the volume of CCTV units which gets sold in the world is about 600 million devices. There are about 16 Crores of CCTV cameras, which get deployed globally. India has just about five percent of the market share, which is 25 percent less than China and USA. I personally believe that India has the potential to become the second largest market in the world by 2030.

As population and prosperity metric grow, the demand for the security devices increases vice versa. The sector has tremendous potential for job creation both indirectly and directly. We have to take opportunities from the geopolitical changes. We must understand that our goal is not just to cater to India but to increase exports as well. India has the potential to become a trusted and reliable partner in this ecosystem. The policies have incentivized domestic production and local manufacturing and also boosted R&D and innovation. The government has given Indian entrepreneurs the confidence to move beyond the comfort zones and the fulfill the dream of Aatmanirbhar bharat. 

Asif Jalal, IPS, IG, (Communication & IT) BSF

In India, every state has a different geography and a different terrain, and it becomes a huge challenge for the security personnel to protect the border. People across the borders are constantly improving new technologies to breach our security modules and soldiers who are guarding the fence. They send explosive devices, illegal guns, and other narcotic devices. Another challenge we face seriously with electronic devices such as drones, which comes to our areas and captures all secretive information. It becomes very difficult to detect due to lack of technology. During the fog, it becomes more difficult to identify it and this is where CCTV cameras play an important role in the entire area. We require more modern surveillance and cameras that can detect the flaws easily. 

Dr. Anand Prakash Maheshwari, Fmr. IPS, Spl Secretary (Internal Security) MHA

 Speaking of national development and security, companies in India are working closely to provide solutions at best. Security and development go hand in hand. The whole security scenario is changing all over the world. Speaking of the technology front, threats are increasing, and power metrics are changing. In the last five years, search engines, crucial components like semiconductors, IoT and AI are also risking cybersecurity and breaches along with development. These technological advancements bring more concerns about the security aspects. Every development comes at some costs. Social networking controls our behavior patterns. Technologies these days are not isolated but rather integrated and electronics is now an important part of whatever we are doing in life. Even in the security sector, electronic components are the crucial element and we will definitely find out ways to grow the components manufacturing sector.

A Simple Automatic Plant Watering System without Microcontroller

Nowadays, many people are turning towards green solutions to lead healthier lives. Efforts are being made to grow plants, which contribute to maintaining the stability of nature. The key challenge in growing plants is maintenance, particularly ensuring they receive adequate watering. Despite our best intentions, we may forget to water our plants at times. To address this, we have developed a very simple automatic plant watering system without Arduino. The idea is to use minimal components and reduce complexity so that everyone can easily build it. It's an ideal option for anyone who is trying to automatically water their potted plants during a vacation 

Let’s see, how we can do that!

Features of Automatic Plant Watering System Project:

  • Based on commonly used BC547.
  • Easy to build.
  • No need for coding.
  • Low-cost design.
  • Easy availability of components.
  • Has a built-in adjustable delay function.

Required Components are listed below to build the simple Automatic plant watering system,

  • Soil Moisture Sensor - x1
  • BC547 - x3
  • Electrolytic Capacitor - 680uf - x1
  • Resistor -

  • Mini Water Pump (3-6v)  - x1
  • Mini Water Tube suitable for pump- Required Length.
  • 5V Power Source - Any

Circuit Diagram Indoor Automatic Plant Watering System:

Below is the circuit diagram of the Automatic plant watering system, as you can see this circuit diagram was so simple and beginner-friendly. If you are not comfortable using components like transistors and resistors you can try check out our alternate project which uses Arduino for Automatic Plan watering system

Here, the soil moisture sensor is the main component to detect the presence of water in the soil. You can visit our Well written article to learn how the soil moisture sensor works. You may think that with the addition of a single transistor to switch the motor, our circuit can be completed, but yeh here are still two transistors used. It looks simple at the beginning but if you think carefully there is the problem that if the motor is turned on for a very short duration it might trigger the motor more often and there will be a need for proper watering of the plant. 

 

Circuit Diagram of Automatic Plant Watering System

So, to solve this issue we are utilizing the simplest timer circuit known as RC Timer Which can be seen below. Depending on the value of the resistor and capacitor we can make the time delay of up to a few seconds. As an advantage, we added a potentiometer to make this time delay adjustable.

RC Timer

Next, you can understand that the Transistor Q1 is used to discharge the capacitor whenever the HIGH signal is received from the Soil Moisture sensor. The output from the RC Timer is Connected to the Q2, which here works as an inverter. So therefore, I am using Q3 to drive the motor. 

You may confuse that Q2 itself can drive the motor instead of being an inverter. Yeah, of course, it can be used to drive a motor if your sensor provides Low for Dryness. But Most of the sensors out there will provide High for Dryness and Low for Wetness. You can refer to the table provided below for a brief understanding.                         

Sensor Input Sensor Output Inverter Requirement Expected Water Pump State
Wetness HIGH YES OFF
Wetness LOW NO OFF
Dryness LOW YES ON
Dryness HIGH NO ON

Components Assembly of the Automatic Plant Watering System:

To make this simple our preference is to make use of breadboard. If you think to make it more stable you can also solder it to a Dotted PCB and keep it in any small enclosure. You can see the assembled image of the components, made in the breadboard below. We Increased the length of the Wire given in the water Pump and talking about the pump I appreciate you checking the perfectness of the waterproofing of the motor, if not make a proper seal by yourself using some sort of gum or even hot glue works well.

Assembling the Components of Plant Watering System

And the main thing we need to discuss here is Power supply. This circuit was made in a way to accept 5V DC input. There are numerous ways to power this circuit like using DC Power Adapters, Mobile chargers, Power banks, etc. I am using a Micro USB Breakout Module to power up the circuit using a USB Cable Connected with the power bank, which can be seen below.

Circuit Connected

Ensure that the Proper Connections are made between the components and then we can start the installation.

I selected a small indoor plant pot and installed the humidity sensor along with the tube from the water pump, and the water pump itself was placed in the bottle with the big mouth so that the motor could be installed straightaway. The remaining circuit was placed near the pot and powered by the power bank. This Setup can be seen below.

Exploring RFID Chip Implants: Legal, Medical, and Ethical Considerations in India

It was in January 2024, when Neuralink Corp. a company by Elon musk implanted its first brain chip called “Telepathy” in a 29-year-old accident victim to help him regain control of his paralyzed limbs. While this technology could actually help humans achieve a cyborg status it is far away from being available as of today

But the same cannot be said for RFID chip implants. The procedure of inserting a tiny RFID chip capsule in-between your thumb and index finger is getting to increase popular among tech enthusiasts. There are nearly more than 6000 people in Sweden who have had a chip insert already and is also catching up into other courtiers like Germany which also has more than 2000 chip implants done already 

We decided to cover an article on RFID chip implants when we noticed that RFID chip implants are also catching up in India, and there are people who have already received an implant in India. The article aims to answer the most basic questions like how does this tech work? How does it affect daily life? Is it legal? Is it medically safe? Etc.

What is an RFID chip Implant why are people getting one?

RFID technology is not new; in fact, most of us have experienced it in one way or another. RFID access cards are very popular in corporate offices to provide access to employees, RFID tags are popular in dress shops to prevent shoplifting, and there are even RFID key fobs that can lock or unlock your vehicle. So yes, we all have been using RFID in one form or another.

RFID Chip

The idea of RFID chip implants is to extend the same technology as a biological chip implant. Instead of you having to carry different cards for digital access, you can implant an RFID tag, and this tag carrying your personal identification can be used to unlock doors, turn on your car, or even make payments. Sounds like a tech from the future, right? Except it's not, RFID chip implants are currently being used in pets and cattle to track them, but in recent days, there is a huge community of people who are using the same. What is even more scary? Most of this procedure is done as a DIY. Yes, let's talk more about it.

RFID Chip Implant can Open Doors, start a Bike and even Share Insta. Profile 

Meet Mithun Devaiah, an engineer from Bangalore who has gotten RFID chips implanted in both of his hands. As shown in the video above, with this implant and a little bit of hardware tinkering, he is able to turn on his bike, open office doors, and even share his Instagram all with a single swipe of his hand.

As a hardware enthusiast Mithun, was exploring around Arduino and RFID technology when he stumbled across RFID chip implant and how it is used in animals. After learning that it can be used for humans, he purchased it online and tried approaching doctors to have it implanted. But since there was not much awareness about it, he implanted these chips by himself by watching online tutorials and has been using his implanted chip for almost two years now. When Circuit Digest asked him about any disadvantages of using the chip, he replied:

Getting an RFID Chip Implant 

Getting an RFID chip implant is easier that it should be. I am writing this article from India, and it took five minutes of google search to find an RFID implant chip that I can use myself, that’s it no medical prescription needed, its available just like that. As you can see in the below picture the RFID implant chip gets shipped with a syringe and is ready to use out of the box.

Cip with Syringe

I in no means want to encourage people to use these, so the vendors name will be hidden. But the points are it can be purchased by anyone with an internet and few bucks to spare. 

Self-Injecting RFID Chip 

This is where things got scary at least for me. These RFID chips are not implanted by doctors but is it done as a DIY procedure. Yes, there are tons of videos out there which shows how a person can inject these RFID tags by themselves. 

Injecting RFID Chip

People who are enthusiastic about it claim that the procedure is relatively safe, and the capsule is being inserted under the skin between your thumb and index finger. This place supposedly has no bones nearby and the chip itself can stay there without restricting any normal activities. While this is not comfortable for a person like me, there are people who have taken this daring step to get an RFID chip implanted. 

Are RFID Chip Implants Safe? – Doctors Perspective

Despite seeing a lot of people successfully self admistering RFID chips and reading through a lot of assuring answers from the online community, we wanted to get a professional Opinion.  Luckily, we were able to find Dr. Vishal Mishra, who was kind enough to answer few questions about what might go wrong with an RFID implant India.  

Vishal Mishra

Q1. Can this RFID chip Implant be self-administered? As a doctor what is your advice?

The mere fact that you showed me this syringe and that its widely accessible and people are already using it as self-admiration is scary. I see cases in wards, and emergency departments every day and sometimes even trained people can get things wrong during a medical procedure. So yes, if you ask me, I would say self-administration for an RFID Chip Implant is scary. 

Q2. Will people with RFID chip Implants be able to take MRI scans?

There are no particular guidelines for an RFID chip Implant and MRI scanning. So, the first reaction would be from the grounds of rejection. MRI machines are expensive and sensitive, so even if someone wants to help you, they will have their doubt. What if the RFID chip gets magnetized or heated, or in worst case pulled out of your skin and into the machine. I am not sure what materials is used in these devices, but considering safety and lack of awareness a person with Chip Implant might very well be rejected for an MRI scan. 

Q3. Assume someone with RFID chip Implant, wants to get it removed. Would you attend it? Is there any legal complication? 

I have been practicing medicine in new Delhi for quite some time, and if someone comes to me with such complication, there is no legal complication or law that will stop me as a doctor from helping the patient to reverse that situation. We see lot of cases with foreign body insertion, especially in elementary canal or in accidents. So, there is no law stopping us from helping them. When someone needs it to be remove, we will help them with most septic and precautionary method possible. 

It will be a simple procedure, unless something is already broken inside, and the parts are scattered. In that case we have to salvage the tissue and sometimes it can even lead to amputation. 

Q4. If someone who is very interested in this technology walks into a clinic and asks help to get the RFID Tag safety injected will you help them?

As a doctor I would have to ask WHY? Are the benefits surpassing the risks associated with it? Even if I am convinced, I will not do it. I would send the person to a therapy or counseling. So yes, absolutely not. 

Can RFID Chip Implants be Hacked?

Apart from the Medical and Legal complications. Another common question is, can this RFID chip be hacked?

The RFID implant tags are a type of passive RFID tag, meaning they do not have a battery or any power source of their own. They have to come in contact with a frequency from an RFID reader to be able to send out the data stored in it. 

The frequency rage of the RFID chip implant tags is very low, around the 125KHz and 13.5Mhz. Low frequency means low range, this is why you have to place your tag very close to the reader for it work. While there are high frequency RFID tags which can operate in long range (like Fastag), almost every RFID chip implants operate on the low frequency. This means that for your tag to be hacked or even read, it has to come in very close proximity to the reader. Also, each RFID has a unique hardware ID which cannot be dublicated.

As confirmed by Rupesh Surve, a hardware security researcher. RFID tags operating on 125KHz and 13.6MHz are for small range (upto 10cm) applications and it cannot be read even by hackers without getting into close proximity. But RFID technology by itself is very vulnerable. The are several tools and methods available using which one can simply clone the RFID Tags. 

Long story short, RFID chips are reliable for applications which does not require high security, but it is not the safest technology to store sensitive data. 

Conclusion – Should you get an RFID Implant?

Unfortunately, the answer to this question is outside the scope of this article. We wrote the article with an intention to educate people who are curious about RFID implants.

That being said, we hope you enjoyed reading this. If you have any questions leave them in comment section and we will discuss your thoughts.
