<p>A tilt sensor includes a body (110), a light emitting diode (120), a first photosensitive element (130), a second photosensitive element (140), and a moving element (150). The body (110) can tilt in a plurality of tilt directions. The light emitting diode (120) is disposed at the body (110) for providing a light beam. The first photosensitive element (130) is disposed at the body (110) and at the opposite side of the light emitting diode (120). The second photosensitive element (140) is disposed at the body (110) and at another side of the light emitting diode (120). The moving element (150) is disposed at the body (110). When the body (110) tilts toward different tilt directions (P1-P4), the moving element (150) moves toward different tilt directions so that different light receiving situations are produced.</p> |
