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 variation is larger than the specific value during the power-saving mode, the working mode is performed.
