1. A proximity sensing method, comprising:
generating a move baseline data according to a detection data;
generating a movement signal according to the detection data, the move baseline data and a move threshold;
generating a proximity baseline data according to the detection data;
generating a proximity signal according to the detection data, the proximity baseline data and a proximity threshold; and
generating a judging signal according to the movement signal and the proximity signal, the judging signal indicating an object proximity or a human body proximity.
