Application tips: inclination measurement
In this application, the acceleration is used to measure an inclination. This inclination is
related to the angle achieved by the gravity’s direction. Thus, if the device is put horizontally,
the gravity will induce a 1 g value on the z axis and the acceleration measured on the other
two axes will be equal to 0, meaning no angle (0°), no inclination.
Description
When there is no movement, the acceleration by default is called gravity and is always
present. On the surface of the earth, the gravity is around 9.81 m/s
Figure 21. Earth's gravity
If the device starts to move from the horizontal position, the gravity will no longer be equal to
1 on the z axis and a value on the x or y axis will be different to 0.
