1. A method for controlling a proximity sensor, comprising:

  • outputting, a driving signal with a preset timing and a preset duty cycle, to a transmitting end and a receiving end of a proximity sensor, controlling the transmitting end to be in a sleep mode, an off mode, and an on mode periodically, and controlling the receiving end to be in a sleep mode and a sampling mode periodically;

    controlling an analog-digital converter in the receiving end to store a first input signal, in a sampling period of the receiving end when the transmitting end is in the off mode; and

    controlling the analog-digital converter in the receiving end to clear the first input signal from a received second input signal, and outputting a first intensity value corresponding to the second input signal after the clearing process, thereby determining a proximity sensor is selectively in an approaching state or a leaving state based on the first intensity value, in a sampling period of the receiving end when the transmitting end is in the on mode.
