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.
This sample locates presence sensors and reads data from them. It includes the following scenarios:
- Obtaining the default presence sensor
- Choosing a presence sensor from among the available sensors
- Letting the user choose a presence sensor
- Detecting the arrival and removal of presence sensors
- Presence sensor data events
- Polling presence sensor readings
Presence Sensor Data Events
When you click the "Get default sensor" button, the app will display data from the default presence sensor, updating it in real time.
Polling Presence Sensor Readings
When you choose the "Get a sensor" button, the app will find all presence sensors and choose one to use. It will then read and display the current reading from that sensor.
Choosing a Presence Sensor
When you choose the "Use picker" button, the app will use a DevicePicker to let the user choose a presence sensor. When one is chosen, the app displays the current reading from that sensor.
When you choose the "Start watcher" button, the app will use a DeviceWatcher to identify all the presence sensors and monitor their arrival and removal in real time. If you select a sensor from the list and click "Read selected sensor", the app will read and display the current reading from that sensor.
