3.6. Magnet Sensor (45-2020)
The Magnet Sensor detects a magnetic field and returns the strength based on the
distance away from the sensor. When the returned value is increasing, the sensor is
detecting the north pole of the magnet. If the value returned is decreasing, then the
sensor is detecting the south pole magnet. The sensor value ranges from ≈0 to ≈700
where 340 indicates no magnetic field.
