温室环境监控警报系统毕业论文

摘 要随着信息技术的飞速进展以与人们生活水平的大幅度提高，人们对生活质量的要求也越来越高，温室的使用越来越广泛，几乎涉与到了生活的方方面面，因此，对温室的要求越来越高，那我们如何对温室的环境进行了解和监控？本文介绍了一款智能化的温室环境监控报警系统，它集温度与湿度的采集于一体，可实现温湿度的自动检测与蜂鸣器提示报警，简单方便，操作容易。自动检测部分是用温度传感器和湿度传感器分别对温度和湿度进行检测，把检测的结果送到单片机。在单片机设置好温度与湿度的报警门限，并与输入单片机的数值进行比较（应当注意的是湿度是以频率的形式输入，必须换算成湿度值才能与单片机预设值进行比较），当超过预设的门限时，蜂鸣器报警，温度与湿度值在 LCD 显示屏上显示出来，同时显示出来的还有当前输入单片机的频率值和温度报警围。本系统还可以通过手动调节报警温度的门限，调节的结果可以在显示屏上显示出来，与其方便简单，具有很强的有用性。关键词：报警系统；温室；湿度传感器；LCD1602AbstractWith the rapid development of communication technique and great improvement of standard of people’s living ， people's quality of life becomes increasingly demanding，the use of greenhouse become more and more widely，almost relate to all aspects of life，so the requirements of the greenhouse getting higher and higher ， how to know the greenhouse environment and monitor it for us? This article introduction an intelligent greenhouse environmental monitoring alarm system ， the temperature and humidity are set in one collection ， it can automatically detect the temperature and humidity and the buzzer alarming ， simple and easy to operate. Automatic detection is that the temperature sensor and humidity sensordetect to temperature and humidity，sent the results of detection to the single-chip. In the single chip ， set up the alarm threshold of temperature and humidity ， compared with numerical which input to the single-chip (note that the humidity which input on the form of...
