Electronic Thermometer Schematic Diagram

An electronic thermometer circuit diagram with high measurement accuracy, memory and beep tips for human body temperature.

 

The electronic thermometer consists of a temperature sensor, an LCD monitor, a button battery, a special integrated circuit and other electronic components.

 

Compared with the traditional mercury glass thermometer,electronic thermometer can measure the body temperature quickly and accurately,has the advantages of convenient reading, short measurement time, high measurement accuracy, energy memory and buzzing cues. The circuit of the electronic thermometer is shown as below, thermal power RT stares and R1, R2, R3 and RP1.When the temperature is 20 ℃, select R1, R3 and adjust the RPL to make the bridge a balance.
