Animation of a gyro wheel in The DMP acquires data from accelerometers, gyroscopes, and additional 3rd party sensors such as magnetometers, and processes the data. It is also much easier to understand and use than a Kalman filter. The code in this repository integrates the gyroscope output (or rather, angular rate data) generated by, for example, an Adafruit LSM9DS0 board using a quaternion method. What you need is probably the accelerometer, and you can see some answers here, for example: Read x y z coordinates of android phone using accelerometer. They can be set to alert on over/under thresholds, data ready, or FIFO overruns. A gyroscope sensor is a device that can measure and maintain the orientation and angular velocity of an object.
