	Sensor	Description
HW	Accelerometer	Measures acceleration force applied to the device, including gravity
	Ambient temperature sensor	Measures ambient room temperature
	Magnetometer	Measures ambient geomagnetic field along three axes
	Barometer	Measures ambient air pressure
	Gyroscope	Measures device rotation along three axes
	Light sensor	Measures ambient light level (illumination)
	Proximity sensor	Measures proximity of an object relative to the screen of a device
	Humidity sensor	Measures humidity of ambient environment
SW	Linear acceleration	Measures acceleration force applied to the device (gravity excluded)
	Gravity sensor	Measures gravity force applied to the device, along three axes
	Rotation	Measures the orientation of a device by providing the 3 elements of the devices’ rotation vector
