This is a 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 (Isolated) in form of analog output for both AC and DC signals in accordance with the current passing through the ‘IN’ and ‘OUT’ pins on the board. 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 the analog voltage. Thick copper conductor and signal traces allow for the survival of the device up to 3-5 times overcurrent conditions. The device requires 5VDC for VCC.
