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 ...

An Arduino library to interact with the ACS712 Hall effect-based linear current sensor. Includes DC and RMS AC current measuring. Supports ACS712-05B, ACS712-10A, ACS712-30A sensors. Typical ...

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 ...

Monitoring the current taken by a mains-powered appliance can be a challenge, particularly if the application demands an inexpensive solution that must provide galvanic isolation for user safety.
