What are the Accelerometers? Describe some applications of Accelerometers.


Accelerometers (acceleration sensors) are used to measure acceleration, vibration, and mechanical shock. Acceleration is the time rate of change of velocity with respect to a reference system. Acceleration is a vector quantity, and is closely related to velocity and displacement.

Some applications of accelerometers include the following:

  1. Sport watches: When runners wear sport watches, their acceleration and speed can be determined by watches that contain accelerometers. 
  2. Digital cameras: Some digital cameras contain accelerometers to determine the orientation of the photo being taken. 
  3. Rockets: Accelerometers are used in rocket design to maintain the rocket’s stability. 
  4. Vehicles: Accelerometers are used widely in vehicles to measure motion of the vehicle. A typical application is that accelerometers can help decide whether air bags should be deployed.
