Inclination measurement

The calculation of an angle with higher resolution and accuracy should take place on a PC. The sensors
used are capable of an accuracy of less than 0.1°.
Since the angle values are derived from the acceleration values, which are subject to certain noise, they
have to be filtered via suitable algorithms.
In simple cases this could be a sliding average value, for example.
