How an IMU works

MPU6050 IMU used in this tutorial

An IMU works based on MEMS techonology, at the minimum it collects both angular velocity and acceleration for 6 degrees of freedom(DOF), although there are more advanced ones that include a barometer(if knowing height relative to ground is important) and magnetometers(very useful for accurate gyroscope values). The accelerometer works on the principle of piezo electric effect, the ability of certain materials to generate an electric charge in response to applied mechanical stress.
