These aren't really items that you use such as an app. They are built in features that provide functionality to the phone.

A brief explanation of each shamelessly copy/pasted from the web:

Gyroscope

• Provides the orientation (or attitude) of the device, it's much more accurate and reliable than accelerometers for this purpose.

Accelerometers

• Provides the magnitude and direction in which the device is moving. As the name implies, it measures the acceleration along any given axis.
• Can be used to determine orientation of the device if you use accelerometers along 3 or 4 axis, but is significantly less accurate and prone to errors.

Compass

• As the name implies, it provides you your heading. It is aligned assuming you're holding the device face up and the top of the device away from you.
• Input from the Gyroscope and Accelerometers allow for more reliable compass readings should your device not be oriented flat and face up.

Barometer

• Provides barometric pressure to aid in determining your altitude. Knowing your altitude can speed up a GPS lock. I'm not entirely sold on the success of this yet, since barometric pressure is not a constant with altitude.

An example of everyday functionality using a couple of these features:

Proximity: usually a tiny sensor located next to the earpiece/speaker. When blocked, the phone display turns off. This is useful when making phone calls to prevent accidental screen touches from the phone against your face.

Gyroscope: Rotating the device allows the screen to rotate accordingly to the position you are holding the device in. IE: landscape/portrait.

Compass/Accelerometer/Barometer: Useful for accurate mapping/GPS/speed/etc....
