Frequently Asked Question
Technically, all these sensors are made with acceleration chips that measure g-forces (gravitational forces), hence the 'G’ in the name. The gravitational force of the earth is a special form of g-force.
An inclination sensor measures the angle with respect to the horizon in which the imaginary line from the center of the earth serves as a reference. The tilt switch uses this line to switch when a certain angle is reached and the acceleration sensor measures g-forces such as the gravitational force in the direction in which the sensor is sensitive (1, 2, or 3 axes).
