20A ACS712 Current Sensor

The 20A ACS712 Current Sensor is a compact and dependable solution for accurately measuring both AC and DC currents up to ±20 A in electronic circuits and embedded systems. Built around the popular ACS712 Hall-effect linear current sensor IC, this module detects current flow by sensing the magnetic field generated by the conductor, providing precise measurements without making direct electrical contact with the high-current path. This design ensures electrical isolation between the load and the measurement circuitry, enhancing safety and protecting sensitive components.

The sensor outputs an analog voltage that is directly proportional to the measured current, making it simple to interface with microcontrollers such as Arduino, ESP32, STM32, and Raspberry Pi using standard ADC inputs. Its high accuracy, stable linear response, and fast reaction time make it suitable for real-time monitoring and control applications.

With its compact and lightweight form factor, the 20A ACS712 module is easy to integrate into a wide range of projects, including power monitoring systems, motor control circuits, battery management systems, inverters, and general DIY electronics. It is an ideal choice for hobbyists, students, and professionals who need reliable current measurement with safe electrical isolation.
