LightSensor

Light sensor sample

This sample shows how to use the Windows.Devices.Sensors.LightSensor API.

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 Data Events option, the app begins streaming light-sensor readings in real time.

Poll LightSensor Readings

When you click the Enable button for the Polling option, the app will retrieve the sensor readings at a fixed interval.
