This project measures real-time voltage and current from a DC load using an ACS712 Hall-effect current sensor and an analog voltage divider connected to an Arduino. The data is read by the Arduino’s ...

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 ...
