Intelligent Control System of Root Layer Water-Fertilization in Greenhouse Based on Wireless Sensor Network

Based on the situation that our nation is seriously lack of water and excessive use of fertilizers，for the object of saving water and rational fertilization，by collecting temperature and humidity in soil，temperature and humidity in air，light radiation，according to crop information analysis system of plant cultivation expert，to make decision required amount of irrigation water and fertilizers.Solenoid valves，pipes，nano-porous tube and the negative pressure of the root layer automatically adjust the control of the water and fertilizer supply，to Automate root layer of micro-irrigation，optimize the growth of plant growth environment，improve water use efficiency.According to the characteristics of farness，disperse and inconstancy of agriculture in China，the design of greenhouse information collection monitoring and control system is presented based on the technology of ZigBee wireless sensor technology，the ARM embedded technology，the Internet network and modern information management.A variety of information collection，management，analysis and dissemination to provide new ideas，new means for the greenhouse monitoring system.
