Level

The electronic spirit level using the accelerometer and magnetometer to determine position of the device, the program can operate in three modes, inclination in the X and Y - the level plane, inclination in the X - the level of the line and inclination in the Y axis - vertical lines.

NOTE

Level is only as accurate as the precise is the accelerometer and magnetometer in your device, using spirit level increases battery consumption by the high sampling rate, which is necessary to achieve a smooth frame rate.

To be sure the appropriate readings, perform calibrations for each of the three modes separately.
