Every mobile device is embedded with some sensors inside, while manufacturing. These sensors ease the working of the applications that are downloaded on to the device. There are basically two types of sensors- physical and composite. Physical sensors are the actual sensors that are embedded in the device such as accelerometer gyroscope and magnetometer. It is not compulsory that every android device should consist of all the three. It depends on the manufacturer and the purpose of the device. Composite sensors are derived by the combination of various physical sensors, such as rotation vector sensor which uses accelerometer, magnetometer and gyroscope. Permissions are set by the android operating system (AOS) to access these sensors. So, for an application to use a sensor, like GPS, it has to request the user to grant permission. Zero permission sensors (ZPS) are those that do not require any permission from the user, and the application can access them without any permission. Such sensors are usually the hardware sensors like accelerometer, gyroscope and magnetometer.

GPS, AOS, ZPS, gyroscope, magnetometer, accelerometer.
