Accelerometers

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 user’s head

• Analog or PWM (Pulse Width Modulated) output

• Can measure 360° by mounting 2 accelerometers perpendicular
