Sensors
What are Sensors? Everything what can get information about an environment, action or object can be called a sensor.
What are Sensors? American National Standards Institute (ANSI) Definition: “A device which provides a usable output in response to a specified measuring”. A sensor acquires a physical parameter and converts it into a signal suitable for processing (e.g. optical, electrical, mechanical).
Need for Sensors Sensors are omnipresent. They embedded in our bodies, automobiles, airplanes, cellular telephones, radios, chemical plants, industrial plants and countless other applications.
Categories of Sensors
Security Default sensors are off. Windows OS warns you how sensors can affect private user information. Administrator access is required to activate the sensor. Once activated, the sensor can operate on all connected user programs. The application that uses the sensor can call the window where the user can activate the sensor. Sensor drivers are objects that process all I/O requests (does not allow unauthenticated users to receive sensor information).
How do Sensors work The DDI enables Windows to provide a standard way for sensor devices to connect to the computer and to provide data to other subsystems. The Windows Sensor API provides a set of methods, properties, and events to work with connected sensors and sensor data. The Windows Location API, which is built on the Windows Sensor API, provides a set of programming objects, including scripting objects, for working with location information. The Location and Other Sensors Control Panel enables computer administrators to set sensors, including location sensors, for each user.
