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 ...

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.

A decent current measurement sensor ought to be an essential part of every hacker’s workbench. One that is capable of measuring DC, as well as low and high frequencies with reasonable accuracy. And ...

Fluxgate current sensors have emerged as a robust technology for the measurement of both alternating and direct currents, harnessing the non-linear magnetic characteristics of ferromagnetic materials.
