语音报警温湿度监控仪系统原理设计
摘 要
随着电子技术的迅速发展，特别是随大规模集成电路的出现，给人类生活带来很大的改变。尤其是有关单片机技术应用的产品走进了千家万户，其中温湿度更是工业生产中常见的被控参数,因此对温湿度控制系统进行研究是具有很广泛的意义。
本文从硬件和软件两方面介绍MCS-51单片机温湿度控制系统的设计思路。而我通过本次设计了解到如何设计单片机温湿度控制及设计的方法和步骤，同时也进一步加深了对单片机温度控制的了解，为以后的学习和工作积累了许多宝贵的经验。

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.
