摘　　要：针对中小型温室提出一种低成本、低功耗的实用型土壤湿度监控系统,采用分布式检测控制方法,借助无线数传技术搭建了主从单片机湿度监控系统,设计了微控制器人机交互电路和程序,实现了土壤水分的精确自动化监测和微灌控制。结果表明,该系统低功耗,宜配置,工作稳定,温室灌水利用率达到0.65,比漫灌节水50%以上。With the development of modern science and technology, China＇s greenhouse automation would he improved at a certain degree. However, because of the complexity or cost of equipment and other issues, the majority of small and medium-sized greenhouse management was still manual. A low-power, low-cost and practical soil moisture monitoring system for small and medium-sized greenhouse was presented. The systems used the structure of master-slave microcontrnller plus wireless data-transmission. It achieved a soil moisture monitoring and precision micro-irrigation. Greenhouse achieved the purpose of water-saving and raising-revenue.
