The XLoBorg library only provides access to the RAW values of the MAG3110 device, which provides a measure of how strong the magnetic field on each of the axes is. To determine the direction of the sensor, we can use the readings from the x and y axes (assuming that we have mounted and calibrated the sensor horizontally). The readings of the x and y axes are proportional to the magnetic field in each direction around the sensor, as shown in the following diagram:

The magnetometer measures the strength of the magnetic field on each axis

The angle at which we turned away from the north can be calculated with the ...
