ACS712 5A Current Sensor Module

The ACS712 5A Range Current Sensor Module is a Hall-effect based current sensing module designed to measure both AC and DC current in electronic circuits. It provides an isolated analog output signal proportional to the detected current, making it ideal for monitoring power consumption, battery systems, motor loads, and embedded electronics applications.

Based on the ACS712ELC-05A current sensor IC, this module can measure current in the range of -5A to +5A and provides a linear analog output that can be read by Arduino, ESP32, Raspberry Pi, STM32, and other microcontrollers through an ADC input. The sensor operates using the Hall Effect principle, providing electrical isolation between the measured current path and the control circuit.

The ACS712 5A module is commonly used in robotics, solar power monitoring, battery management systems, smart energy meters, and DIY electronics projects requiring real-time current measurement.
