Abstract
This paper describes the design principle and implementation method of digital thermometer and voltmeter based on STC89C52 microcontroller and temperature sensor. The temperature is measured through DS18B20, and the current voltage is detected through ADC0832 cooperating with the voltage detection circuit. Hardware includes: power circuit, display circuit, temperature acquisition circuit, voltage detection point circuit, key circuit, LED lamp circuit, etc. The biggest feature of the system is that its software design uses hierarchical and modular design methods. After debugging and testing, all performance parameters of the system fully meet the design indicators. The system is programmed with C language, which is easy to maintain and modify. The whole function of the digital thermometer system is introduced; Secondly, it introduces the hardware module circuit design of each module, explains the selection and application of corresponding components, and expounds the control principle and software debugging of each part.
Key words: STC89C52 single chip microcomputer; DS18B20 temperature sensor; LED lamp; Digital thermometer.
