The A3144 Hall Effect Sensor Magnet Detector Switch for Arduino is a digital output Hall-effect sensor that operates at 5V DC. It can detect both poles of a magnet and has an output voltage equal to the operating voltage. With an operating temperature range of -40C to 85C, this sensor is suitable for automotive and industrial applications.

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

An onboard LED indicates the presence of a magnetic field. When no magnetic field is present, the signal line of the sensor is HIGH at 3.5V. In the presence of a magnetic field, the signal line goes LOW, and the LED on the sensor lights up.
