Description
The 20A Range Current Sensor Module is a precise and efficient sensor designed to measure AC and DC current up to 20A. Built using the ACS712 Hall Effect-based sensor, it provides analog voltage output proportional to the current passing through it. This module is widely used in motor control, power monitoring, energy management, and battery charging systems. Its compact design, high accuracy, and electrical isolation make it a perfect choice for Arduino and other microcontroller-based applications.
