About this product

Hall Effect Sensor A3144 Magnet Detector Switch for Arduino is a switch that will turn on/off in the presence of a magnetic field. If no magnetic field is present, the signal line of the sensor is HIGH (3.5 V). If a magnetic field is presented to the sensor, the signal line goes LOW, at the same time the LED on the sensor lights up. An onboard LED will also indicate the presence of a magnetic field.

Pin Connection

Connect the Powerline (middle) to +5V and ground (-) to GND. Connect signal (s) to any digital pin on the Arduino .
