involves three concepts:Roll: left and right tilt angle, also called Rolling Angle http://baike.baidu.com/view/1769672.htmPitch: front and back tilt, also called the pitch angle http://baike.baidu.com/view/3832041.htmYaw: Left and Right swing, also called yaw angle http://baike.baidu.com/view/1769448.htm The following

(angle [2]); // The direction sensor provides three data types: azimuth, pitch, and roll.//// Azimuth: returns the angle between the magnetic pole and the Y axis at the normal time, ranging from 0 ° to 360 °.// 0 ° = North, 90 ° = east, 180 ° = South, 270 ° = West.//// Pitch: the
