An accelerometer sensor is a sensor that can measure acceleration. It is usually composed of masses, dampers, elastic components, sensitive components, and adaptive circuits. In the process of acceleration, the sensor obtains the acceleration value by using Newton's second law, measuring the inertial force on the mass block. According to the different sensitive components of the sensor, common accelerometer sensors include capacitive, inductive, strain gauge, piezoresistive, piezoelectric and so on.
