The term internet of things was coined only in 2008, but within the next 10 years (in 2018) there were already more than 7 billion IoT devices connected to the internet, and the number is set to increase exponentially. IoT has enabled multiple inter-connected devices to sense and transfer data wirelessly over the internet to provide vital data and control in areas like Home automation, Location tracking, Asset monitoring etc..
This section provides a wide variety of IoT Projects with complete resources including circuit diagram and code, allowing you to build and test your own IoT applications. It also discusses the recent IoT Technology Trends and keeps you updated with the latest IoT News.
Digi-Key Electronics announced that it has partnered with Truphone to bring cellular IoT connectivity services to manufacturers worldwide. The partnership will provide customers with connected cellular devices and a fully managed service.
Digi-Key will use Truphone’s state of the art SIM technology, allowing users to connect IoT devices to…
Canada based I-SYST has come up with a tiny nRF52840 module that is as small as a fingernail. Named BLYST840, the module has 46 I/O, 1 MB flash, 256 kB RAM, is ready for Bluetooth 5.2, is Thread, and ZigBee capable, NFC-enabled, comes with built-in security measures and supports MicroPython. The nRF52840 ARM Cortex-M4F module is feature-rich with ultra-low-power SoM that…
Previously we built a smart container using weight as a measurement parameter to send alerts. Now in this IoT smart jar, we will check the level of a Jar using Ultrasonic sensor and send an alert email to the user. The level of Jar will also be displayed on a webpage hosted on NodeMCU ESP8266.
This smart Jar allows us to keep track of the stocks,…
A crude way to power your DC circuits with AC mains is to use a step-down transformer for stepping down the 230V mains voltage and adding a couple of diodes as a bridge rectifier. But due to the huge space size and other drawbacks, it cannot be used for all purposes. Another most popular and professional way is to use Switch Mode Power Supply Circuits for converting your AC…
We previously used NodeMCU to log temperature data in the Google sheet. Now here we are going to send data to Thinger.io IoT cloud and display it in an attractive graphical format. A BMP180 sensor is interfaced with NodeMCU ESP8266 to collect the temperature, humidity, and altitude data, which will be sent to the Thinger.io platform. In this tutorial, we will learn how…
Selecting the right communication medium is usually a very challenging part of the development of any IoT solution. In situations where range beyond that of Wi-Fi and Bluetooth is required, options are usually between the LPWAN technologies like LoRa, Sigfox, etc. but while these technologies come with Pro-IoT features like low power and long-range, they are saddled with…
The benefits of getting two machines (or components within them), to talk to one another have been an obvious one to Industrial automation and control experts, way before the Internet of Things (IoT) became mainstream. The values in a temperature sensor at the heart of a crankshaft sending measurements to control the motor drive relay etc. was clear, and one of the…
Renesas introduced the RA4W1 microcontroller (MCU) with an integrated Bluetooth 5.0 Low Energy radio, which includes a 48 MHz, 32-bit ArmCortex M4 core and Bluetooth 5.0 core delivered in a 56-pin QFN package. The RA4W1 MCU allows the designers to develop safe and secured IoT endpoint devices for Industry 4.0, building automation, metering, healthcare, consumer wearable…
Artificial Intelligence is a revolutionary technology that we all have been well acquainted with for quite some time now. In our previous article, we have already discussed the progress of Artificial Intelligence and understood its outstanding phenomenon and groundbreaking technology that is strongly transforming how business operations take place across various business…
In today’s world of cutting-edge technologies, Digital Image Processing is growing very fast and become an important part of many digital devices like mobile, security cameras, laptops, etc.
The most common applications of Digital Image Processing are object detection, Face Recognition, and people counter. So in this tutorial, we are going to build…
Espressif has launched ESP32-Korvo, an ESP32 and ESP-Skainet based AI development board for embedded IoT devices. The board is designed with multiple peripherals, earphones, speakers, an SD card slot, LED lights, and function buttons, all of which can serve a variety of AI-powered voice applications. ESP32-Korvo features a multi-microphone array that is suitable for far-…
The ESP32-based M5Stack ATOM from Espressif is the smallest (24 x 24mm) development board available in the market, which is designed for portable embedded systems and IoT development projects. M5Stack is the most cost-effective product due to its small size and there is no battery integrated to it. The M5Stack has two types of units in the ATOM series, ATOM Matrix, and ATOM…
