20A Range ACS712 Current Sensor


ACS712ELCTR-20A Module Arduino ACS712 20A Range Current Sensor Module

The 20A-range ACS712 Current Sensor 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 the customer. Typical applications include motor control, load detection and management, switched-mode power supplies, and overcurrent fault protection. The device consists of a precise, low-offset, linear Hall sensor circuit with a copper conduction path located near the surface of the die.


  • The current sensor chips are: ACS712ELC-20A;
  • Pin 5V power supply, on-board power indicator;
  • The module can measure the positive and negative 20 amps, corresponding to the analog output of 100 mV/ A;
  • The test current through the output voltage is VCC / 2;
  • PCB board size: 31 mm  x 13 mm;;
  • Color: as the photo shows.
