农业大棚温湿度监控系统设计

Design of Temperature and Humidity Monitoring System for Agriculture Greenhouse

为了提高农业大棚的自动化程度和生产效率,设计了一种农业大棚温湿度监控系统。该系统以AT89S52单片机为控制核心,采用性价比较高的温湿度传感器,实现了对农业大棚温湿度的测量与控制。针对不同的作物,可以通过键盘设定环境温度和湿度的上、下限值。当检测到温湿度参数越限时,系统启动声音报警,并通过输出继电器控制执行机构对温湿度进行调节。系统软件采用C语言进行设计,并且实现了模块化设计。该系统具有检测精度高、运行可靠、使用方便等特点。

In order to improve automation degree and production efficiency of agriculture greenhouse,the temperature and humidity monitoring system for agriculture canopy were designed.This system took AT89S52 single chip as control core,and a temperature humidity sensor with high quality was used to realize the measurement and control of temperature and humidity of agriculture greenhouse automatically.Moreover,the upper and lower limit of ambient temperature and humidity can be set by keys according to different crops.An audible alarm was touched off and output electric relays were powered to control the adjustment of temperature humidity by executive devices when the temperature and humidity parameters were out of the threshold.The system software was designed by using C language and the block-based design was realized.With high detection accuracy and operation reliability,the system was easy to use by operators.
