Figure 22. Inclination measurement
In this example, the device has an
The y axis is not affected and the acceleration measured will remain equal to 0.
However, for the x axis, the acceleration measured will move from 0 and will be equal to
1g*sin( ).
For the z axis, the acceleration measured will be 1g*cos( ).
