+ \class QCompassReading
+ \ingroup sensors_reading
+ \inmodule QtSensors
+ \since 1.0
+
+ \brief The QCompassReading class represents one reading from a
+ compass.
+
+ \section2 QCompassReading Units
+ The compass returns the azimuth of the device as degrees from
+ magnetic north in a clockwise direction based on the top of the UI.
+ There is also a value to indicate the calibration status of the device.
+ If the device is not calibrated the azimuth may not be accurate.
+
+ Digital compasses are susceptible to magnetic interference and may need
+ calibration after being placed near anything that emits a magnetic force.
+ Accuracy of the compass can be affected by any ferrous materials that are nearby.
+
+ The calibration status of the device is measured as a number from 0 to 1.
+ A value of 1 is the highest level that the device can support and 0 is
+ the worst.
