Use getSensorList(int) to get the list of available Sensors. SensorManager A class that permits access to the sensors available within the Android platform. SensorEventListenerAn interface used for receiving notifications from the SensorManager when sensor values have changed. An application implements this interface to monitor one or more sensors available in the hardware. SensorEventThis class represents a sensor event and holds information such as the sensor type (e.g., accelerometer, orientation, etc.), the time-stamp, accuracy and of course the sensor's data. MediaRecorderA class, used to record media samples, that can be useful for recording audio activity within a specific location (such as a baby nursery). Audio clippings can also be analyzed for identification purposes in an access-control or security application. For example, it could be helpful to open the door to your time-share with your voice, rather than having to meet with the realtor to get a key.GeomagneticFieldThis class is used to estimated estimate magnetic field at a given point on Earth, and in particular, to compute the magnetic declination from true north. FaceDetectorA class that permits basic recognition of a person's face as contained in a bitmap. Using this as a device lock means no more passwords to remember — biometrics capability on a cell phone.Sensor and SensorManagerSensor and SensorManagerSensor type (Sensor class)◦Orientation, accelerometer, light, magnetic field, proximity, temperature, etc. Sampling rate ◦Fastest, game, normal, user interface. ◦When an application requests a specific sampling rate, it is really only a hint, or suggestion, to the sensor subsystem.
