Infrared sensing module, terminal device, and control method of terminal device

A terminal device, comprising an infrared sensing module, wherein the infrared sensing module comprises a reflecting portion, a driving portion, an infrared light emitter and an infrared light receiver;

• the terminal device further comprises a processor, a memory, and a computer program stored in the memory and executable on the processor, wherein the computer program, when executed by the processor, causes the terminal device to perform:
• driving, via the driving portion, the reflecting portion to rotate;
• determining whether an intensity of an infrared signal received by the infrared light receiver meets a preset condition;
• and
• fixing a position of the reflecting portion in a case that the intensity of the infrared signal meets the preset condition.

A non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium stores a computer program, and the computer program, when executed, causes a terminal device to perform:

• driving, via a driving portion of the terminal device, a reflecting portion of the terminal device to rotate;
• determining whether an intensity of an infrared signal received by an infrared light receiver of the terminal device meets a preset condition;
• and
• fixing a position of the reflecting portion in a case that the intensity of the infrared signal meets the preset condition.
