This sensor device is built to measure the amount of current being used, especially in power supplies as the design is based on Arduino. The main component used is the ACS712 sensor from Allegro ...

Working Principle of ACS712 Current Sensor with Arduino The ACS712 sensor operates on the Hall-effect principle. When current flows through the input terminals (IP+ and IP-), it generates a magnetic ...

An Arduino library to interact with the ACS712 Hall effect-based linear current sensor. Includes DC and RMS AC current measuring. Supports ACS712-05B, ACS712-10A, ACS712-30A sensors. Typical ...

Schematic of the ACS712 Current Sensor Circuit (tested circuit diagram of the current sensor module) The internal resistance of this conductive path is 1.2 mΩ typical, providing low power loss. The do ...

If you've always wanted to try to build an Arduino project, this may be a great way to start. Matt Williamson built a tiny, Arduino-based motion sensor that will SMS you when something moves by ...

Here is an ultra simple Arduino Night Alarm project wired around a handful of inexpensive and easily available components. One advantage of using Arduino as a security system is the flexibility!

The Arduino IR sensor module code is very simple and easy to understand. We are just keeping track of whether the input to pin D9 is HIGH or LOW. We initialize our code by declaring two global ...

Simple Proximity Sensor. 18 Comments . by: Mike Szczys. April 20, 2012. Title: ... He wanted a standalone sensor for his Arduino projects which would use a single pin as a trigger.

The idea is simple enough: just place a INA219 current sensor between the power supply and the microcontroller under observation, and record the resulting measurements as it goes about its business.
