ACS712 10A Current Sensor Module

The ACS712 10A Current Sensor Module is based on Hall-effect sensing technology, allowing it to measure electrical current flowing through a conductor without direct electrical contact with the measurement circuit. The sensor outputs an analog voltage proportional to the current, which can be read by a microcontroller’s analog input pin. The module also provides electrical isolation between the high-current path and the control circuit, improving safety and reliability. Because of its compact size and accurate sensing, the ACS712 module is widely used in energy monitoring systems, power supply monitoring, motor control systems, and battery management applications.
