Soil health monitoring, irrigation scheduling, hi-tech greenhouses, evapotranspiration studies, watershed management, land reclamation, drought, flood forecasting, etc. play a vital role in farming. Farmers in India have been facing a lot of problems in terms of real-time and on-field data analytics. Undoubtedly, there are certain companies that offer the solution but the…
For the last many years, automobile manufacturers have turned their attention towards self-driven cars. It all became serious when Google launched its self-driving car project (Wamyo) in 2009. A few years later, Elon Musk announced Tesla would build a self-driving system into its cars and in November 2018, Tesla launched a feature called Navigate on Autopilot. By 2013, major…
Direct Online Starter or DOL is a simple electromechanical system designed for switching and protection of Induction motors.
We all know that motors consume electric power horribly and this high power consumption is the result of current drawn by the winding of the motor. So higher the current drawn by the motor, the higher will be the power…
A superheterodyne receiver uses signal mixing to convert the input radio signal into a steady intermediate frequency (IF) that can be worked with more easily than the original radio signal, which has a different frequency, depending on the broadcasting station. The IF signal is then amplified by a strip of IF amplifiers and then fed into a detector that outputs the audio…
Transport is one of the major contributors to global warming, representing more than 23% of global energy-related carbon dioxide emissions. Today, Electric Vehicles are looked upon as an alternative green way of commutation but to make EVs more affordable and practical, we need much more efficient batteries and battery-charging technology.

We know that voltage, current, and power are measured in volts, amps and, watts and voltmeter, ammeter, and wattmeter are used to measure these parameters. Though these measuring instruments are manufactured with the care they may still give error readings at the customer end. So these instruments are calibrated to minimize the error. Here in this article, we will explain…
A True-RMS or TRMS is a type of converter which converts RMS value to equivalent DC value. Here in this tutorial, we will learn about true RMS to DC converter, how it works and how measurement methods can affect displayed results.
What is RMS?RMS is the abbreviation of Root Mean Square. By definition, for alternating electric current, the RMS value…
In today’s case study, we have a cement plant, where four dilution air fans (2 fans in each of the 2 units of the kiln) of 225 KW and 744 RPM is under operation. After five years of operation, one of the current motor (fan) was planned to be replaced with the spare motor which was there in the store for the last 4 -5 years. This was planned because the current…
Would you want to swallow electronics? Yes, you heard that right! Electronics, in general, are not meant to be eaten. They have toxic and indigestible materials and if they get stuck inside a human body, they can lead to serious internal damage. However, researchers around the globe are working towards making the electronics that you can swallow. In fact, there is one such…
In commercial and industrial environments, it’s essential to house electrical devices in a secure enclosure. Such devices include controls such as power supplies, terminals, relays, fuses, and many others.
The underlying reason for selecting & utilizing an electrical enclosure is to prevent airborne particles such as debris or dirt as well as…
Developing a new hardware product is no doubt a herculean task filled with uncertainties which if not properly managed, could increase the project’s lead time, delay the launch, and cost the company tons of money.
Large Corporates usually have the experience, relationship, money, and people bandwidth to mitigate these risks, but for startups and…
As applications based around Wireless Sensor Networks, Home Automation, and IoT increased, the need for alternative communication protocol asides the regular Bluetooth, Wi-Fi, and GSM protocols was becoming obvious. Several technologies like Zigbee and Bluetooth Low Energy (BLE) were developed as alternatives but one standout technology, developed to specifically serve home…
