The ACS712 20A current sensor is designed to measure electrical currents up to 20A using Hall effect technology. It provides an analog voltage output proportional to the detected current, allowing easy integration with microcontrollers. The sensor features electrical isolation, ensuring safety while handling high currents. It is commonly used in industrial automation, power monitoring, and energy management systems. The ACS712 offers high accuracy, fast response, and minimal power consumption. Operating at 5V, it can measure both AC and DC currents efficiently. The module is compact and widely used in renewable energy applications.
