Gyrometer Gyrometer Gyrometer Gyrometer Gyrometer Class


Represents a gyrometer sensor.

This sensor returns angular velocity values with respect to the x, y, and z axes.

For an example implementation, see the gyrometer sample.

public : sealed class Gyrometer : IGyrometer, IGyrometer2, IGyrometerDeviceId
struct winrt::Windows::Devices::Sensors::Gyrometer : IGyrometer, IGyrometer2, IGyrometerDeviceId
public sealed class Gyrometer : IGyrometer, IGyrometer2, IGyrometerDeviceId
Public NotInheritable Class Gyrometer Implements IGyrometer, IGyrometer2, IGyrometerDeviceId
// This class does not provide a public constructor.
Windows 10 requirements
Device family
Windows 10 (introduced v10.0.10240.0)
API contract
Windows.Foundation.UniversalApiContract (introduced v1)


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.

The following example demonstrates how a UWP app built with XAML and C# uses the GetDefault method to establish a connection to a gyrometer. If no integrated gyrometer is found, the method will return a null value.

_gyrometer = Gyrometer.GetDefault();

The following example demonstrates how a UWP app built with XAML registers a ReadingChanged event handler.

private void ScenarioEnable(object sender, RoutedEventArgs e)
    if (_gyrometer != null)
        // Establish the report interval
        _gyrometer.ReportInterval = _desiredReportInterval;

        Window.Current.VisibilityChanged += new WindowVisibilityChangedEventHandler(VisibilityChanged);
        _gyrometer.ReadingChanged += new TypedEventHandler<Gyrometer, GyrometerReadingChangedEventArgs>(ReadingChanged);

        ScenarioEnableButton.IsEnabled = false;
        ScenarioDisableButton.IsEnabled = true;
        rootPage.NotifyUser("No gyrometer found", NotifyType.StatusMessage);

The following example shows the ReadingChanged event handler.

async private void ReadingChanged(object sender, GyrometerReadingChangedEventArgs e)
    await Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
        GyrometerReading reading = e.Reading;
        ScenarioOutput_X.Text = String.Format("{0,5:0.00}", reading.AngularVelocityX);
        ScenarioOutput_Y.Text = String.Format("{0,5:0.00}", reading.AngularVelocityY);
        ScenarioOutput_Z.Text = String.Format("{0,5:0.00}", reading.AngularVelocityZ);


DeviceId DeviceId DeviceId DeviceId DeviceId

Gets the device identifier.

MaxBatchSize MaxBatchSize MaxBatchSize MaxBatchSize MaxBatchSize

Gets the maximum number of events that can be batched by the sensor.

MinimumReportInterval MinimumReportInterval MinimumReportInterval MinimumReportInterval MinimumReportInterval

Gets the minimum report interval supported by the gyrometer.

ReadingTransform ReadingTransform ReadingTransform ReadingTransform ReadingTransform

Gets or sets the transformation that needs to be applied to sensor data. Transformations to be applied are tied to the display orientation with which to align the sensor data.

ReportInterval ReportInterval ReportInterval ReportInterval ReportInterval

Gets or sets the current report interval for the gyrometer.

ReportLatency ReportLatency ReportLatency ReportLatency ReportLatency

Gets or sets the delay between batches of sensor information.


FromIdAsync(String) FromIdAsync(String) FromIdAsync(String) FromIdAsync(String) FromIdAsync(String)

Asynchronously obtains the sensor from its identifier.

GetCurrentReading() GetCurrentReading() GetCurrentReading() GetCurrentReading() GetCurrentReading()

Gets the current gyrometer reading.

GetDefault() GetDefault() GetDefault() GetDefault() GetDefault()

Returns the default gyrometer.

GetDeviceSelector() GetDeviceSelector() GetDeviceSelector() GetDeviceSelector() GetDeviceSelector()

Gets the device selector.


ReadingChanged ReadingChanged ReadingChanged ReadingChanged ReadingChanged

Occurs each time the gyrometer reports the current sensor reading.
