This sample shows how to use the Windows.Devices.Sensors.LightSensor API.
Note This sample was created using one of the universal app templates available in Visual Studio. It shows how its solution is structured so it can run on both Windows 8.1 and Windows Phone 8.1. For more info about how to build apps that target Windows and Windows Phone with Visual Studio, see Build apps that target Windows and Windows Phone 8.1 by using Visual Studio.
This sample allows the user to view the ambient light reading as a LUX value. You can choose one of two scenarios:
- LightSensor data events
- Poll light sensor readings
LightSensor Data Events
When you click the Enable button for the LightSensor data events option, the app begins streaming light-sensor readings in real time.
Poll LightSensor Readings
When you click the Enable button for the Poll light sensor readings option, the app will retrieve the sensor readings at a fixed interval.
To obtain an evaluation copy of Windows 8.1, go to Windows 8.1.
To obtain an evaluation copy of Microsoft Visual Studio 2013 Update 2, go to Microsoft Visual Studio 2013.
Note For Windows 8 app samples, download the Windows 8 app samples pack. The samples in the Windows 8 app samples pack will build and run only on Microsoft Visual Studio 2012.
