"2021-2022单片机温度控制电路设计与制作精品专题资料"

Based on single-chip microcontroller temperature control circuit design and production, this project utilizes the STC89C52RC as the control core, with the real-time clock chip DS1302 and digital temperature sensor DS18B20 forming a system that controls high and low temperatures separately. The hardware structure, working principle, and software program design of the entire system are detailed, with a focus on the modular design and production of the clock module, display module, temperature detection module, and related control modules. The system uses an LCD1602 as the display screen, showing real-time time, ambient temperature, and the temperature values on the hour for the past 24 hours. All software programs in this design are written in C language for easy portability and upgradeability. Key words include STC89C52RC, single-chip microcontroller, DS1302, LCD1602, and temperature control.
