ACS712 30A Current Sensor Module

The ACS712 30A Current Sensor Module uses Hall-effect sensing technology to measure electrical current flowing through a conductor. The sensor produces an analog voltage output proportional to the current, allowing microcontrollers to measure current safely.

Because the sensor provides electrical isolation between the sensing circuit and the control circuit, it is suitable for measuring both AC and DC currents. The module is compact, reliable, and widely used in power monitoring systems, battery management systems, and energy measurement projects.
