An accelerometer is a device that measures the vibration, or acceleration of motion of a structure. Modern accelerometers are often small micro electro-mechanical systems (MEMS). Accelerometers gauge proper acceleration, which is the rate of change of velocity with regards to time. Modern accelerators, such as those integrated in circuit boards, can measure vibration, shock, and tilt of moving objects. Depending on the sensing mechanism and their designated purpose, there are several types of accelerometers.
