The project published here is a high-voltage adjustable regulator with an output 48 V DC from an input supply of 125V DC. The circuit is capable to drive load current up to 500mA. This regulator circuit designed for use in high-voltage applications where standard bipolar regulators...

Project Goal: To measure the atmospheric pressure using one of the best modules i,e BMP280 Pressure sensor module. Components Used in the Project: Arduino Uno BMP280 Connecting Wires LCD 16 X2 BMP280 Pressure Sensor Module The BMP280 sensor module operates with...

This reflective sensor module is a high-performance 0-5 cm active proximity detector. The sensor can provide a range up to 50cm with higher current infra-red LED and current limit resistor R2, R4 used across IR LED. Because the sensor operates on an absolute reflectance threshold...

Flow rate and volume helps tell the amount of fluid going into, or through a particular vessel. For certain process automation applications, this simple-sounding fluid measurement task is so critical to the success of the project that, failure to get it right, could bring the entire...

One of the best things about being a maker is the ability to make your own tools. We have covered the development of several electronics tools in past, from voltmeters to battery testers. For today's tutorial, we will add another tool to the list by examining the development of a Miliohm...

This project includes an analog Hall Effect sensor and an Op-Amp circuit which can be used as position or angular sensing with the benefits of no contact and wearing, high stability and wide sensing range. Two configurations of the magnet and Hall sensors are analyzed. Trimmer...

I'm a big fan of the ESP32 boards because of the number of communication options they managed to squeeze on the board, but I became more impressed recently when I came across the TTGO LoRa32 development boards which adds LoRa to the onboard communication features of the ESP32. The...

A few years back I wrote this tutorial on connected weather monitor with plans of creating a 3D printed enclosure to make it portable and easy to use. I never got around doing that but a few days ago, I came across a similar project built by BitsandBlobs, which went as far as creating the...
