System.Sensors
Sensors are pieces of hardware or software that can provide measures of physical quantities to your applications. This unit provides classes and components that let you obtain information and manage system sensors.
This unit provides the following sensor classes and components:
Class | Component |
---|---|
It also provides access to related services. For example, TGeocoder and TGpsStatus provide access to geocoding and GPS services respectively, both services related to the TCustomLocationSensor.
The TSensorManager class lets you identify the sensors connected to the computer and make them available for use within applications.
