Overview

The ACS712 Current Sensor Module is a compact and practical solution for adding current measurement to electronics, robotics, automation, and embedded projects. Based on the Allegro ACS712 Hall-effect current sensor, it can sense both AC and DC current and produces an analog output that varies with the measured current.

The ACS712 uses a low-resistance internal copper conduction path and magnetic sensing, allowing the current-carrying path to remain electrically isolated from the sensor's signal circuitry. Depending on the specific ACS712 variant, available sensing ranges include ±5A, ±20A, and ±30A, with typical sensitivities of 185 mV/A, 100 mV/A, and 66 mV/A respectively.It is suitable for projects involving motor current monitoring, load detection, power-supply monitoring, overcurrent experiments, and general AC/DC current measurement.
