An optical sensing device includes a shell, at least one light emitting member, a rotator type shading member and at least one optical sensing member. The shell is formed with a black-body condition space having a light emitting chamber, a shading chamber and at least one optical sensing chamber. The light emitting member projects a light beam. The rotator type shading member is rotatably restrained within the shading chamber, and has a geometric center and a weight center offset from the geometric center. When the optical sensing device is lifted in a lifting azimuth or lowered in a lowering azimuth, the rotator type shading member is rotated by the geometric center to make the weight center located in the lowering azimuth with respect to the geometric center. The optical sensing member is arranged in the optical sensing chamber, and senses the light beam to accordingly send out a sensing signal.

摘要:
An operation method to operate a tilt sensor with power-saving mechanism is provided. The operation method comprises the steps as follows. An accommodating space is provided such that a blocking object is displaceable in the accommodating space according to the gravity. A working mode is performed such that a light-emitting element emits light according to a first current and at least two first light sensors sense a light amount to determine a tilt angle of the tilt sensor. When the light amount doesn't change or when a light amount variation sensed by a second light sensor is smaller than the threshold value within a predetermined time period, a power-saving mode is performed such that the light-emitting element emits light according to a second current smaller than the first current. When the light amount variation is larger than the specific value during the power-saving mode, the working mode is performed.
