Acceleration is calculated the difference between two successive velocities
divided by the time between the samples (according to the sampling rate).

The motion sensor uses a very sophisticated method that enables it to measure
long distance range with a low power of pulses.

In this experiment, we shall use it at distance range and we assume its ID is 1 as
the default ID. Selecting the range should be done with the NeuLog software.
