android.hardware.SensorManager	A class that permits access to the sensors available within the Android platform. Not every Android-equipped device will support all of the sensors in theSensorManager, though it's exciting to think about the possibilities. (See below for a brief discussion of available sensors.)
android.hardware.SensorListener	An interface implemented by a class that wants to receive updates to sensor values as they change in real time. An application implements this interface to monitor one or more sensors available in the hardware. For example, the  in this article contains a class that implements this interface to monitor the orientation of the device and the built-in accelerometer.
