To measure the hall-effect sensor’s output at higher currents, one must either have a higher current power supply or, more wire wraps inside core of the sensor. This design idea explores the latter ...

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 ...

Connect the ACS712 current sensor module according to this diagram. Therefore, must connect the ACS712 current sensor output to an ADC pin of Arduino.

What new integration would you wish to have? I would like to have the possibility to use an ACS712 current sensor with esphomelib and esphomeyaml. The sensor allows you to read the current of a ...

Melexis has announced a magnetism-based current sensor that needs no ferromagnetic core, for measuring currents through power PCBs and busbars (see diagram). MLX91235 is gradiometric, taking a ...
