Examples

For an example implementation, see the inclinometer sample https://github.com/Microsoft/Windows-universal-samples/tree/master/Samples/Inclinometer.

Remarks

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 an inclinometer. If no integrated inclinometer is found, the method will return a null value.

_inclinometer = Inclinometer.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 (_inclinometer != null)
    {
        // Establish the report interval
        _inclinometer.ReportInterval = _desiredReportInterval;

        Window.Current.VisibilityChanged += new WindowVisibilityChangedEventHandler(VisibilityChanged);
        _inclinometer.ReadingChanged += new TypedEventHandler<Inclinometer, InclinometerReadingChangedEventArgs>(ReadingChanged);

        ScenarioEnableButton.IsEnabled = false;
        ScenarioDisableButton.IsEnabled = true;
    }
    else
    {
        rootPage.NotifyUser("No inclinometer found", NotifyType.StatusMessage);
    }
}

The following example shows the ReadingChanged event handler.

async private void ReadingChanged(object sender, InclinometerReadingChangedEventArgs e)
{
    await Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
    {
        InclinometerReading reading = e.Reading;
        ScenarioOutput_X.Text = String.Format("{0,5:0.00}", reading.PitchDegrees);
        ScenarioOutput_Y.Text = String.Format("{0,5:0.00}", reading.RollDegrees);
        ScenarioOutput_Z.Text = String.Format("{0,5:0.00}", reading.YawDegrees);
    });
}
