Description The A3144 Hall Effect Sensor Magnet Detector Switch for Arduino is designed to function as a magnetic field switch that activates in the presence of a magnet. When no magnetic field is detected, the sensor’s signal line remains HIGH at approximately 3.5V. However, when a magnetic field is introduced, the signal line goes LOW, and an onboard LED lights up to indicate the presence of the magnetic field. This makes it an effective and user-friendly option for various projects where detecting magnets is required, allowing for easy integration with Arduino and other microcontroller platforms.
