gyroscope sensor determines
rotational velocity of the device in each
axis.
use values obtained from the
gyroscope sensor to determine the
orientation of the device in space
if you are interested in determining the
attitude (yaw, pitch, and roll) of the
device, use Motion
gyroscope sensor is not required for
Windows Phone devices; your phones
do not have it

Senses→has
gyroscope
Indicates if the
gyroscope is available
on the device
Senses→has motion
Indicates if the motion
can be computed on
the device. Motion
requires
accelerometer,
compass and
gyroscope.

Motion→gravity
Gets the gravity vector associated with
this reading.
Motion→acceleration
Gets the linear acceleration of the
device, in gravitational units.
Motion→yaw
Gets the yaw of the attitude in degrees
Motion→pitch
Gets the pitch of the attitude in degrees
Motion→roll
Gets the roll of the attitude in degrees
Motion→rotation speed
Gets the device rotation speed in
degrees per sec.
Motion→time
Gets a timestamp indicating the time at
which the reading was calculated.
