Abstract:
1. A tilt sensor, comprising: a body suitable for tilting in a plurality of tilt directions, comprising: a light emitting device (LED) disposed in the first containing region, the LED suitable for providing a light beam; a first photosensitive device disposed in the second containing region and arranged on a side of the LED; a second photosensitive device opposing to the first photosensitive device and disposed in the third containing region and arranged on another side of the LED; and a reflective moving thin-element disposed in the movement region, wherein when the body tilts toward one of the different tilt directions, the reflective moving thin-element is correspondingly moved toward the tilt direction so that the reflective moving thin-element directly reflects the light beam provided from the LED to at least one of the first photosensitive device or the second photosensitive device, or the reflective moving thin-element shields the light beam provided from the LED from being transmitted to the first photosensitive device and the second photosensitive device.
