Abstract:
A proximity sensor module used in an electronic device includes a combination sensing element and antenna, and a detecting circuit electrically connected to the combination sensing element and antenna. The combination sensing element and antenna is used to detect whether an external object is in vicinity of the combination sensing element and antenna according to capacitance changes of the combination sensing element and antenna in presence or absence of an external object in the vicinity, the detecting circuit detects the capacitance changes, and generates a signal associated with the changes to decrease or increase transmission power transmitted to the combination sensing element and antenna.
