The A3144 Hall Effect Sensor Magnetic Detector Switch for Arduino is a switch that turns on and off in the presence of a magnetic field. In the absence of a magnetic field, the sensor signal line is HIGH (3.5 V). If the sensor has a magnetic field, the signal line will go LOW and the sensor LED will light up at the same time. The built-in LED also indicates the presence of a magnetic field.
Features of A3144 Hall Effect Sensor Module:
- Digital Output Hall effect sensor.
- Operating voltage: typically 5V.
