The A3144 Hall Effect Sensor Module is a digital magnetic switch sensor used to detect the presence of a magnetic field. It works based on the Hall Effect principle, where the output changes when a magnet comes close to the sensor. This makes it ideal for position detection, speed measurement, and contactless switching applications.
It is widely used in Arduino, ESP32, robotics, and industrial automation projects.
