Accelerometer Working Principle

Accelerometer Working Principle

Accelerometers measure linear acceleration and also gravity; the two are indistinguishable.

Thus they unavoidably function as tilt sensors as well. Inexpensive 1, 2, and 3-axis accelerometers are available which are constructed with MEMS techniques.

MEMS gyroscopes are also available, for measuring angular velocity, but are more expensive.
