The A3144 Hall Effect Sensor 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.
