The A3144 Hall Effect Sensor Module is an essential workshop sensor engineered for detecting magnetic fields in electronics prototypes and automation systems. Built around the popular A3144 unipolar Hall-effect switch, it responds to the presence of a magnetic pole (such as a neodymium magnet) by switching its digital output state.
The module integrates an onboard status LED, a filtering capacitor, and a pull-up resistor, providing a clean, stable digital signal (HIGH/LOW) that interfaces directly with microcontrollers like Arduino, ESP32, and Raspberry Pi. It is widely used for non-contact position sensing, speed measurement, and tachometer applications.
