ACS712 Current Sensor Module — Hall Effect Based AC/DC Current Measurement
The ACS712 Current Sensor Module uses Allegro's ACS712 Hall effect IC to measure AC or DC current with high accuracy and full galvanic isolation. Whether you're building an energy monitor, a battery management system, or an overcurrent protection circuit, this module delivers clean analog output directly readable by Arduino, ESP32, or any ADC-equipped microcontroller.
