摘  要

 隨著電子技術(shù)的迅速發(fā)展，特別是隨大規(guī)模集成電路的出現(xiàn)，給人類(lèi)生活帶來(lái)很大的改變。尤其是有關(guān)單片機(jī)技術(shù)應(yīng)用的產(chǎn)品走進(jìn)了千家萬(wàn)戶(hù)，其中溫濕度更是工業(yè)生產(chǎn)中常見(jiàn)的被控參數(shù),因此對(duì)溫濕度控制系統(tǒng)進(jìn)行研究是具有很廣泛的意義。
 本文從硬件和軟件兩方面介紹MCS-51單片機(jī)溫濕度控制系統(tǒng)的設(shè)計(jì)思路。而我通過(guò)本次設(shè)計(jì)了解到如何設(shè)計(jì)單片機(jī)溫濕度控制及設(shè)計(jì)的方法和步驟，同時(shí)也進(jìn)一步加深了對(duì)單片機(jī)溫度控制的了解，為以后的學(xué)習(xí)和工作積累了許多寶貴的經(jīng)驗(yàn)。

ABSTRACT

    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.
