Abstract
The present invention is related to a method for proximity sensing and an applied electronic device thereof. The present invention provides that a movement signal is generated according to a detection data, a move baseline data and a move threshold and cooperated with a proximity signal for generating a judgement signal to judge if the human body or the object body is close to the electronic device.
