Second, the working principle of the ear thermometer/forehead thermometer

Using the characteristics that all objects greater than zero will emit infrared light, a special infrared sensor sensor (senser) is used to collect the infrared light emitted by the object and convert it into a weak uV~mV level voltage signal. The digital signal obtained by the AD converter is processed by the single-chip microcomputer to obtain the actual temperature, which is expressed through the man-machine interface: LCD display or voice report or data transmission to the computer for centralized processing.
