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 ...

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 ...

A sensor that I somehow missed, despite it being a popular building block in module form is the WCS1800 current sensor from Winson of Taiwan. It is part of a large family of current sensors from the ...
