Member Type Description

GetDefault Method A static factory method that returns a sensor instance.

GetCurrentReading Method Returns a read-only object containing the currently available sensor data.

ReadingChanged Event An event raised when ever the current reading changes.

ReportInterval PropertySpecifies how often the sensor reads new data. The data returned by the GetCurrentReading will only change once every time interval.

MinimumReportInterval PropertyA read-only value specifying the smallest value that can be passed set in the ReportInterval property.

Accelerometer

public sealed class AccelerometerReading{ public double AccelerationX { get; } public double AccelerationY { get; } public double AccelerationZ { get; } public DateTimeOffset Timestamp { get; }}

The acceleration along the each axis in g’s.

Gyrometer

public sealed class GyrometerReading{ public double AngularVelocityX { get; } public double AngularVelocityY { get; } public double AngularVelocityZ { get; } public DateTimeOffset Timestamp { get; }}

The angular velocity, in degrees per second, about each axis.

Compass

public sealed class CompassReading{ public double HeadingMagneticNorth { get; } public double? HeadingTrueNorth { get; } public DateTimeOffset Timestamp { get; }}

Heading - the angle between the magnetic field, and the direction the device is pointed

Inclinometer and Orientation Sensor

public sealed class OrientationSensorReading{ public SensorQuaternion Quaternion { get; } public SensorRotationMatrix RotationMatrix { get; } public DateTimeOffset Timestamp { get; }}

public sealed class InclinometerReading{ public float PitchDegrees { get; } public float RollDegrees { get; } public float YawDegrees { get; } public DateTimeOffset Timestamp { get; }}

Rotation around each access
