Current Sensor - 50A (AC/DC)

This is a breakout board for the fully integrated Hall Effect based linear ACS758 current sensor. The sensor gives precise current measurement for both AC and DC signals.The module features thick copper conductor that allows it to handle over current conditions.

The ACS758 outputs an analog voltage output signal that varies linearly with sensed current.

FEATURES

• Arduino interface compatible
