In addition, most of the recent digital display thermometer circuit, the digital signal is first through the temperature sensor to collect the temperature, and then through the amplification circuit, amplification circuit after the voltage is connected to a / D converter, the obtained digital signal is finally input into the microcontroller chip, which processes the signal and then outputs the display.
