The ACS712 20A Hall Effect Current Sensor Module is a high-performance current sensing module designed to measure both AC and DC currents up to ±20A. It is built around the ACS712 Hall effect IC, which outputs an analog voltage signal directly proportional to the sensed current.
This module ensures electrical isolation between the measured load and the microcontroller, enhancing both safety and reliability. With an output sensitivity of approximately 100 mV/A, it provides accurate readings that can be easily interfaced with an Arduino, ESP32, STM32, Raspberry Pi, or other microcontrollers.
Ideal for power monitoring, motor control, robotics, and energy metering, this sensor is widely used in both DIY projects and industrial applications.
