Below is an image of Lego WeDo tilt sensor:
Watch this tilt sensor experiment video to observe how the output values changes.
Depending on how it is tilted, the sensor will output different values as follows:
Horizontal: 0
Up: 2
Down: 10
Left: 8
Right: 4
The tilt sensor is useful for detecting tilt for various WeDo models like the rocking sailboat or airplane.
A good illustration of how the tilt sensor can be used would be for 2 legged walking robot for sensing tilt and correspondingly move motor or motors in such a way as to keep balance so the walking robot does not fall down.
