The A3144 Hall Effect Sensor Module is a magnetic field detection module designed to sense the presence of a magnet or magnetic field and provide a digital output signal. It is based on the A3144 Hall effect sensor IC, which changes its output state when exposed to a magnetic field of sufficient strength.
This module operates on a wide voltage range (3.3V to 5V DC), making it suitable for use with Arduino, ESP32, ESP8266, Raspberry Pi, and other microcontrollers. When a magnetic field is detected, the output pin switches state, allowing easy integration into logic-level circuits and control systems.
The board includes an onboard LED indicator that visually shows the detection status, making testing and debugging simple. Thanks to its fast response time, high sensitivity, and stable performance, the module is reliable for both hobby and industrial applications.
