0.36" DC 0-30V 3-Wire Digital Voltmeter Display Module Previous 
The ACS712 Current Sensor Module provides analog current measurement for DC and AC signals. It uses the ACS712ELC-05B chip and outputs a linear analog voltage proportional to the input current. The module is powered from 5V DC and offers a zero-current output voltage of 2.5V. It is designed for current monitoring, motor current measurement, electrical protection, and power-related projects. The board also includes an on-board power indicator and gold plated circuit boards.
