Background

The digital acceleration sensor is used for sensing acceleration, and the acceleration sensor is a sensor capable of measuring acceleration, and generally comprises a mass block, a damper, an elastic element, a sensitive element, an adjusting circuit and the like. In the acceleration process of the sensor, the acceleration value is obtained by measuring the inertial force borne by the mass block and utilizing Newton's second law, common acceleration sensors comprise capacitance type, inductance type, strain type, piezoresistive type, piezoelectric type and the like according to different sensitive elements of the sensor, the piezoelectric acceleration sensor is also called as a piezoelectric accelerometer and also belongs to the inertial type sensor, and the principle of the piezoelectric acceleration sensor is that the piezoelectric effect of piezoelectric ceramics or quartz crystals is utilized, and when the accelerometer is vibrated, the force of the mass block on the piezoelectric element is changed. When the measured vibration frequency is much lower than the natural frequency of the accelerometer, then the force change is directly proportional to the measured acceleration.
