Along with the rapid development of electronic technology, especially with a large-scale integrated circuits, to human life has been a fundamental change. Especially monolithic integrated circuit applications has entered the tens of thousands of households. Industrial production in temperature and humidity are charged with common parameters, the typical temperature and humidity control system to study with a very broad meaning.
In this paper from both hardware and software introduced the MCS-51 microcontroller temperature and humidity control system design, hardware schematic diagram and the process was simple description. Through this design makes me understand how to design SCM temperature and humidity control and design of methods and steps to achieve, but also enabled me to further deepen the understanding of SCM temperature control for future study and work accumulated many valuable experience.
Key word: MCS-51 single-chip; Temperature and humidity control ; Hardware schematic diagram; Flow chart
