on sensor
provides data for the following three dimensions:</p>

<ul>
  <li>Azimuth (degrees of rotation around the z axis). This is the angle between magnetic north
and the device's y axis. For example, if the device's y axis is aligned with magnetic north
this value is 0, and if the device's y axis is pointing south this value is 180. Likewise, when
the y axis is pointing east this value is 90 and when it is pointing west this value is 270.</li>
  <li>Pitch (degrees of rotation around the x axis). This va
