3D Inclinometer

Description

This sensor varies in 2 axes or 3 axes. It can be used as an accelerometer or an inclinometer (tilt sensor).

It is described in far more detail on our page « 2D Accelerometer »

INCLINOMETER = ACCELEROMETER

Angle measure

Angle measure is done by tilting compared to a vertical axis, earth gravity's acceleration direction. The two components, acceleration of a movement and earth's gravity, are indivisible.

The angle measure is more precise if the sensor isn't moving, or only very slowly and without acceleration other than that of gravity.

Case study

Dynamic mode : measures the acceleration of gestures, virtual percussions, danse moves,...
Static mode : measures an angle, a position around an axis, placement of an object, incline of an arm, ...

Settings

Each axis has two settings in order to optimize sensor to each use :

• Gain :  Amplification, affects the sensor's sensitivity to variations in movement or inclination ;
• Rest level, zero : sensor's returned value when set down horizontally, on a flat surface with no movement.

Gain setting is on the side of the white 3 pin connectors.

Rest level setting are on the other end of the card, towards the edge.

The following schema show the adjustment potentiometer's rotation direction.
