There is main TSensorManager class that acts as a gateway to all sensor information. It has a Current: TSensorManager class property that is used to reference all sensor information. At the top of the System.Sensors unit, you can find a TSensorCategory enumerated type that provides the top level categorization of all possible sensors:
type
TSensorCategory = (Location, Environmental, Motion, Orientation, Mechanical, Electrical, Biometric, Light, Scanner);
Within each category there are different sensor types, so each category has its own enumerated type as well. All specialized sensor types derive from an abstract...
