What’s in a Sensor?
Category: What is being sensed? (e.g. Location)
Type: How is it being sensed? (e.g. GPS)
Properties: Model, report interval, friendly name
Data report: Synchronous or asynchronous
Events: State change, data arrived
State: Enabled, access denied

Ambient Light Sensor
Optimize for best user experience
Change screen brightness
Out of the box with Windows 7
Drive adaptive user interface
LCD displays are difficult to read outdoors in direct sunlight
Utilize knowledge of ambient lighting conditions to improve PC usability
Change contrast, color theme, and font size to be more readable in direct sunlight
