北京林业大学本科毕业论文（设计） PAGE \* MERGEFORMAT PAGE \* MERGEFORMAT II 自动喷灌装置的设计与制作 摘要 针对人工灌溉中存在的过量或少量、不及时等不足，本文设计一种基于51单片机和土壤湿度传感器实现计算机控制自动喷灌过程的方案。开始工作LCD将实时显示当前不同两点的湿度信息，用户可以分别设定每点的湿度值，传感器读取的湿度值大于该值+5度，将自动关闭该点相应的继电器从而关闭喷水阀门，当读取湿度值小于该值-5度，自动开启继电器。当读取湿度一直大于设定值+5度或小于设定值-5度一分钟时，发出警报。本系统可用于节水喷灌，对节约水资源、节省人力，效果良好，意义重要，在农林业、物联网有着广泛的应用前景。 关键词：湿度，水喷灌，自动 全套图纸加扣?3012250582 PAGE \* MERGEFORMAT PAGE \* MERGEFORMAT III Design and manufacture of automatic Sprinkling irrigation Electronic information science and technology 11-2 Tang Shi Supervisor ChenYan-xia Abstract For those an excess or a small amount or untimely which exist in artificial irrigation, the paper design a computer controlled automatic sprinkler process scheme which based on 51SCM and humidity sensor. When the system began to work,LCD will display different points of current humidity information in real-time , the user can set the humidity value of each point separately, humidity sensor reading is greater than the value +5 degrees,system will automatically shut down the corresponding relay to close the water valves, when reading the humidity value is less than the value of -5 degrees， automatically open relays. When reading the humidity has been greater than the set value +5 degrees or 5 degrees below the set value over a minute , alarm. This system can be used for water-saving irrigation, to save water, save manpower, to good effect, having a important meaning, in agriculture,forestry, or the internet of things,it have a wide range of applications.
