Accelerometers

• An accelerometer is a device for measuring
  acceleration. An accelerometer inherently
  measures its own motion.
• Accelerometers are used along with
  gyroscopes in inertial guidance systems, as well
  as in many other scientific and engineering
  systems. One of the most common uses for micro
  electro-mechanical system (MEMS) accelerometers
  is in airbag deployment systems for modern
  automobiles. In this case the accelerometers are
  used to detect the rapid deceleration of the
  vehicle to determine when a collision has
  occurred and the severity of the collision.

Accelerometers

• Provide measurement of the acceleration of the
  users head
• Analog or PWM (Pulse Width Modulated) output
• Can measure 360 by mounting 2 accelerometers
