摘要在人们的生活生产中,无不渗透着温度、湿度等相关的重要的因素。因此, 人们对温度、湿度有了一些测量的方法。随着社会的快速发展和科学技术的不断 提高以及产品种类的日益丰富,使得人们对温度、湿度有了更高、更严的标准。 许多高质量的产品更加依赖于可靠和稳定的温湿度环境。于是,对温度、湿度测 量系统的研究,便有了非常重要的意义。 72735
以往对温湿度的监测方法,主要是依靠人工定时监测,并将测量的温湿度数 据进行记录,然后再与标准的温湿度值进行比较,得出相关的结论,再执行相关 的操作,以实现对温湿度的控制。这种比较传统的监测方法不仅浪费了大量的人 力资源,而且所测量的结果也存在着明显的误差。快速发展的科学技术将自动化 控制系统引入了人类的生活生产中。本课题针对传统测量方法的不足,综合利用 了各项先进的技术,构造出一个自动化、高精度、稳定性好、低成本的温湿度监 测系统。
本次设计采用了模块化的设计理念,将温湿度监测系统分为采集模块、显示 模块、设置模块、核心控制模块、报警模块以及监测模块。利用集成温湿度传感 器 SHT15 的测温湿度快,以及使用简便的特点,同时结合单片机 STC89C51 的 强大功能,设计了一个监控系统,来对温湿度进行实时监测。
整个监测系统测量准确,调试方便,可以实时记录报警信息,方便工作人员 排除故障,并可以广泛的应用在许多恶劣的环境中。本次设计的系统只是完成了 对温湿度的监测,并没有实现丢温湿度的控制,但是可以实时精确的监测温湿度。 因此,本次设计具有十分重要的研究意义。

Ultra-low Power Temperature and Humidity Monitoring System Design
Abstract In the production of human life, all permeated with important factors related to temperature and humidity。 Therefore, people have some method of measuring the temperature and humidity。 With the continuous improvement of the rapid development of society and science and technology and increasingly rich product categories, making it the temperature and humidity have a higher and more stringent requirements, many high-quality products more dependent on reliable and stable temperature and humidity 。 Thus, it is very important to study temperature and humidity measurement system。
The conventional method of monitoring temperature and humidity, mainly rely on manual regularly monitored and measured temperature and humidity data to be recorded, then the standard temperature and humidity values, to reach appropriate conclusions, and then executing the operation, in order to achieve control of temperature and humidity。 The more traditional detection methods not only waste a lot of human resources, and the measured results are also obvious error。 The topic for the shortcomings of traditional measurement methods, the utilization of advanced technology to construct an automated, high accuracy, good stability, low cost temperature and humidity monitoring system。
The design uses a modular design concept, the temperature and humidity monitoring system is pided into acquisition module, display module, setup module, the core control module, alarm module and monitoring module。 With integrated temperature and humidity sensor temperature and humidity of the SHT15 fast, easy to use features, combined with a powerful microcontroller STC89C51, we design a monitoring system to control temperature and humidity in real time has been overrun alarm。
