ACS712 20A Current Sensor Module

The ACS712 20A Current Sensor Module is a Hall-effect-based current sensor designed to measure both AC and DC currents up to ±20 A. It operates by detecting the magnetic field generated by the current flowing through its internal conductor and provides a proportional analog voltage output. The module offers electrical isolation between the measured current and the output signal, ensuring safe and reliable operation. It can be easily interfaced with microcontrollers such as Arduino, ESP32, STM32, Raspberry Pi, and PIC through their analog input pins. Due to its high sensitivity, low power consumption, and accurate current measurement capability, the ACS712 20A Current Sensor Module is widely used in power monitoring systems, battery management systems, motor control, overcurrent protection, energy measurement, industrial automation, and IoT-based electrical monitoring applications.
