*
* All values are angles in degrees.
*
+ * Orientation sensors return sensor events for all 3 axes at a constant
+ * rate defined by setDelay().
+ *
* azimuth: angle between the magnetic north direction and the Y axis, around
* the Z axis (0<=azimuth<360).
* 0=North, 90=East, 180=South, 270=West
* All values are in SI units (m/s^2) and measure the acceleration of the
* device minus the force of gravity.
*
+ * Acceleration sensors return sensor events for all 3 axes at a constant
+ * rate defined by setDelay().
+ *
* x: Acceleration minus Gx on the x-axis
* y: Acceleration minus Gy on the y-axis
* z: Acceleration minus Gz on the z-axis
* All values are in micro-Tesla (uT) and measure the ambient magnetic
* field in the X, Y and Z axis.
*
+ * Magnetic Field sensors return sensor events for all 3 axes at a constant
+ * rate defined by setDelay().
+ *
* Proximity
* ---------
*
* the sensor should report its maxRange value in the "far" state and a value
* less than maxRange in the "near" state.
*
+ * Proximity sensors report a value only when it changes. setDelay() is
+ * ignored.
+ *
* Light
* -----
*
* The light sensor value is returned in SI lux units.
*
+ * Light sensors report a value only when it changes. setDelay() is
+ * ignored.
