The Current Sensor ACS712 (20A) module provides economical and precise solutions for AC or DC current sensing in industrial, commercial, and communications systems. 

Typical applications include motor control, load detection and management, switched-mode power supplies, and overcurrent fault protection. This module utilizes the ACS712 hall -Effect Based linear current sensor to measure current using the hall Effect principle.

ACS712 Current sensor can measure current AC or DC current ranging from +20A to -20A. This module outputs Analog voltage(0-5V) based on the current flowing through the wire: hence it is very easy to interface this module with any microcontroller.
Note: When there is no current passing through this module, the output voltage would be at a center voltage of 2.5V.
