This is a small but very effective Linear Current Sensor Module based on fully integrated Hall Effect based linear ACS712 current sensor IC from Allegro. The sensor gives precise current measurement for both AC and DC signals and can be used effectively for max 20A current measurement.

ACS712 chip takes AC or DC voltage at its input and its output varies linearly with sensed current; its output is analog voltage. Thick copper conductor and signal traces allows for survival of the device up to 3-5 times overcurrent conditions. The device requires 5VDC for VCC. It has low noise analog signal path, 5us output rise time in response to input current, IC is Factory-trimmed for accuracy, extremely stable output offset voltage and nearly zero magnetic hysteresis.
