ACS712 Hall Effect Current Sensor Module – 20A

The ACS712ELCTR-20A Hall Effect Current Sensor Module is designed for precise AC and DC current measurement up to 20A. It utilizes a fully integrated Hall-effect linear sensor that provides an analog voltage output proportional to the sensed current at 100 mV/A sensitivity. Operating at 5V DC, the module outputs VCC/2 when no current is present, enabling bidirectional current detection. Its compact breakout design ensures easy integration with Arduino and other 5V microcontroller platforms for monitoring, control, and protection applications.
