ACS712 Current Sensor Module
The ACS712 Current Sensor Module is a Hall-effect based current sensing module designed to accurately measure both AC and DC current in electronic circuits. It provides an analog voltage output proportional to the current flowing through the conductor, making it ideal for use with Arduino, ESP32, Raspberry Pi, and other microcontroller platforms. The sensor offers electrical isolation between the measured current and the output signal, ensuring safe and reliable operation. It is available in 5A, 20A, and 30A current measurement variants for different application requirements.
