ACS712 Current Sensor Module – 5A, 20A, 30A Variants
The ACS712 Current Sensor Module is a compact, Hall-effect based solution for precise measurement of AC and DC currents. Available in 5A, 20A, and 30A variants, it outputs an analog voltage proportional to the sensed current, making it easy to interface with Arduino, ESP32, Raspberry Pi, and other microcontrollers. With galvanic isolation for safety and low noise operation, it’s perfect for energy monitoring, motor control, automation systems, and current-based protection circuits.
