If a person stands on the top end of the doormat body 100, the personnel detection device 300 sends a trigger signal to the main control circuit board 200 to end the sleep mode of the automatic temperature-measuring doormat. The main control circuit board 200 generates a control instruction according to the trigger signal and sends it to the temperature-measuring device 400 to perform the automatic temperature-measuring work. When the person leaves the top end of the doormat body 100, the trigger signal is no longer sent, and the automatic temperature-measuring doormat re-enters the sleep mode. The cooperation of the main control circuit board 200, the personnel detection device 300, and the temperature-measuring device 400 completes the functions of automatic detection and temperature measurement based on the internally programmed routine settings.

If a person stands in front of the doormat body 100, the distance measurement sensor 302 sends a start signal to the main control circuit board 200. If a person stands on the top of the doormat body 100, the pressure conduction disc 303 receives the pressure data transmitted by the pressure sensor 304 and sends a trigger signal to the main control circuit board 200 in cooperation with the start signal, avoiding mis-triggering of the main control circuit board 200.
