Background sensors sample

Shows how to use background tasks with a device-use trigger targetting sensor APIs.

Note: This sample is part of a large collection of UWP feature samples. You can download this sample as a standalone ZIP file from docs.microsoft.com, or you can download the entire collection as a single ZIP file, but be sure to unzip everything to access shared dependencies. For more info on working with the ZIP file, the samples collection, and GitHub, see Get the UWP samples from GitHub. For more samples, see the Samples portal on the Windows Dev Center.

For the sake of the example, the Accelerometer API is used in this sample.

This sample allows the user to view the event count. Only one scenario is available:

• Accelerometer Device Use Trigger

Accelerometer Device Use Trigger

When you choose the Enable button for the Accelerometer DeviceUse option, the app registers a DeviceUseTrigger background task that listens for accelerometer readings and counts them.
