What’s an Accelerometer?

Posted on

Accelerometers are device that measure acceleration, which will be the speed of change of the velocity of an item. They measure in meters per second squared (m/s2) or in G forces (g). One Gforce for us here on planet Earth is equivalent to 9.8 m/s2, but this does vary somewhat with altitude (and will be a different value on different planets due to variations in gravitational pull). Accelerometers are ideal for feeling vibrations in systems or for orientation uses.

An Accelerometer Functions
physical activity monitor are electromechanical devices that feel either static or dynamic forces of acceleration. Electrostatic forces contain gravitation, while forces that are dynamic range from movement and vibrations.
Acceleration can be measured by accelerometers on two, one, or three axes. 3-axis components have become more prevalent as the cost of development for them falls.
Typically, accelerometers feature capacitive plates. A few of these are fixed, although some are attached as acceleration forces act upon the detector to miniscule springs that go internally. The capacitance between them transforms as these plates go in regard to every other. From these changes in capacitance, the acceleration may be ascertained.
Other accelerometers may be centered around piezoelectric substances. These miniature crystal structures output signal electric charge when put under mechanical stress ( e.g. acceleration).
