The Windows.Devices.Sensors namespace has these enumerations.

ActivitySensorReadingConfidence Specifies the confidence of a sensor reading.
ActivityType Specifies activity types of a sensor.
MagnetometerAccuracy The sensor's accuracy.
PedometerStepKind The type of step taken according to the pedometer.
SensorReadingType Specifies the sensor reading type.
SimpleOrientation Indicates the orientation of the device.



This namespace provides access to the sensor types listed in the table below. The driver for a sensor must indicate that the hardware is integrated with the PC chassis for it to be accessible via this namespace. Sensors not marked as PC-integrated, even if they are of a supported type, will not be accessible. Driver developers can refer to SensorConnectionType enumeration for more details.

AccelerometerDetects acceleration along three axes (x, y, and z).
InclinometerDetects angle of incline along three axes (pitch, roll, and yaw).
GyrometerDetects angular velocity along three axes.
CompassDetects heading in degrees relative to magnetic north (and due north when integrated with onboard GPS).
LightDetects ambient lighting level in lumens.
OrientationCombines the data from the accelerometer, compass, and gyrometer sensors to provide smoother and more sensitive rotation data than can be obtained from any of the sensors alone. See the Quaternion and SensorRotationMatrix definitions. This combined sensor data is also known as “Sensor Fusion.”
Simple OrientationUses the accelerometer to obtain device orientation as a rotation into one of four quadrants, or face-up, or face-down.


In addition, this namespace provides access to the following motion (or movement) data.

QuaternionA Quaternion is a rotation of a point [x,y,z] around an arbitrary axis.
Rotation MatrixA Rotation Matrix represents a rotation around 3 axes (x, y, and z).


Sensor data is provided relative to the device's fixed sensor coordinate system, and is independent of display orientation. For applications that rely on sensor data for input control or to manipulate elements on the screen, the developer must take current display orientation into account and compensate the data appropriately. For more info about the sensor coordinate system, see Sensor data and display orientation.
