A current sensor can help us protect our circuits or motors, or even to monitor whether a device is on or not.

This module is based on the ACS712 sensor that works based on the Hall effect principle so it does not interfere with the circuit.

ACS712 current sensor (5A)

  • 5uS fast response

    80kHz bandwidth

    1.5% maximum output error (Ta = 25 ° C)

    1.2mOhms internal resistance

    2.1kVRMS isolation between current measurement pins

    It only takes 5V of power

    Voltage output proportional to current in AC or DC

    185mV / A output
