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 library supports ACS712 current sensor modules of 5A, 20A, and 30A. The ACS712 current sensor module is a fully integrated, hall-effect-based linear current measuring device. It can measure both ...
