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 ...

The Allegro ACS712 provides economical and precise solutions for AC or DC current sensing in industrial, commercial, and communications systems. The device package allows for easy implementation by ...

Allegro MicroSystems' two high-performance, low-noise 2100-Vrms isolation current sensors, the ACS712 and ACS713, provide lower noise and higher accuracy than previous generation current sensors.

Recently, [Solder Hub] put together a brief video that demonstrates the basics of a Hall Effect sensor — in this case, one salvaged from an old CPU fan. Two LEDs, a 100 ohm resistor, and a 3.7 volt ...
