Accelerometers

What is an accelerometer? An accelerometer is a device that measures the vibration, or acceleration of motion of a structure. Accelerometers are used along with gyroscopes in inertial guidance systems, as well as in many other scientific and engineering systems. One application for accelerometers is to measure gravity, wherein an accelerometer is specifically configured for use in gravimetry. An accelerometer inherently measures its own motion (locomotion), in contrast to a device based on remote sensing. The widespread use of accelerometers in the automotive industry has pushed their cost down dramatically.
