Description Current Sensor ACS712 AC and DC Measuring Current 5A, 20A, 30A This is a breakout board for the fully integrated Hall Effect based linear ACS712 current sensor. The sensor gives precise current measurement for both AC and DC signals. This version is optimized to sensing current up to 20A. The ACS712 outputs an analog voltage output signal that varies linearly with sensed current. The device requires 5VDC for VCC and a couple of filter capacitors. We have : ACS712-5A ACS712-20A ACS712-30A
