The acceleration sensor is an electronic device that can measure the acceleration and convert the acceleration to the electrical signal. Expedite is the force of an object in an acceleration process, like the gravity of the earth, that is, the gravity. The acceleration can be a constant, for example, G, and so the variable. There are two kinds of accelerometer: one is the angle accelerometer, which is improved by the gyroscope (angular velocity sensor). The other is the line accelerometer.
The acceleration sensor can be used in industrial control and instrumentation; handle oscillation and shaking, toys, mouse; automobile brake start detection and alarm system; structure and environment supervision; engineering geological exploration, earthquake detection, vibration test and analysis; oscillation of railway, bridge and dam; high-rise building structure dynamic characteristics and safety to defend the oscillation investigation on.
