ion sensor return multi-dimensional arrays of sensor
values
for each <code><a href="../../../reference/android/hardware/SensorEvent.html">SensorEvent</a></code>. For example, the orientation sensor provides
geomagnetic
field strength values for each of the three coordinate axes during a single sensor event. Likewise,
the orientation sensor provides azimuth (yaw), pitch, and roll values during a single sensor event.
