The title says it all – this article describes a microcontroller-compatible current sensor module you can build yourself, using an inexpensive 8-pin chip as an ‘active shunt’ for measuring ac/dc ...

This is a breakout board for the fully integrated Hall Effect based linear ACS712 current sensor. The sensor gives precise current measurement for both AC and DC signals.

This repo contains the esp8266-arduino firmware for the Sonoff S20 which supports to read the ADC pin on which I've connected an ACS712-5A. This firmware is part of my blog post here To build the ...

Working of ACS712 Current Sensor: Before we start building the project it is very important for us to understand the working of the ACS712 Current sensor as it is the key component of the project.

Shaun Milano, Strategic Marketing Manager at Allegro MicroSystems describes the ACS712 low noise Hall Effect current sensor IC with 2100 VRMS voltage isolation, and shows how current sensors work and ...
