Abstract: The present invention relates to a proximity sensor and a proximity sensing method. The proximity sensor includes a sensing element and a sensing circuit. The sensing circuit is coupled to the sensing element and transmits a first driving signal and a second signal to the sensing element, respectively. The sensing element receives the first driving signal and the second driving signal, respectively, and generates a first sensing signal and a second sensing signal, respectively. The sensing circuit generates a proximity signal according to the first sensing signal and the second sensing signal. Therefore, the present invention may improve the accuracy of sensing the proximity of the human body whether near to the sensor. In addition, the sensing circuit is further coupled to a radio-frequency circuit, and the sensing circuit transmits a driving signal or/and receives a sensing signal according to the state of the radio-frequency circuit, thereby reducing interference of the sensing circuit to the radio-frequency circuit.
