I II Abstract At present, the greenhouse agriculture is booming in our country. Every year, the area of greenhouse is increasing at the speed of millions of hectares. Greenhouse agriculture has become irreplaceable in our agricultural industry. In our country, it has a significant contribution to economic growth. However, what does not match with our agricultural country is the outdated technology in the greenhouse agriculture, especially in the field of greenhouse environment monitoring, which greatly limits the development of greenhouse agriculture in China. Therefore, it becomes more and more important to research the greenhouse monitoring system. In connection with the lack of hardware and software in the present greenhouse system, the paper developed an intelligent greenhouse monitoring system, in order to study a functional greenhouse monitoring system with low costs, easy operation and accurate results. The main content and conclusions included five aspects as below: A kind of network structure model with wireless sensor network (WSN) was put forward, based on the research on the architecture of greenhouse environment monitoring system. A series of subsystems, including temperature sensor system, humidity sensor system, light intensity sensor system and image sensor system, were designed, according to the need of the monitor system structure of greenhouse. The hardware design and the software design of the terminal node based on CC2430 were completed, studying the design proposal of greenhouse terminal node system. The paper designed the power supply module of CC2430, realizing the feed circuit between lithium-battery solar battery-charging circuit and the other modules, completed the circuit monitoring environment parameters of greenhouse, such as temperature, humidity, light and so on; and accomplished ad hoc networks based on CC2430 wireless sensor network, making the wireless data transmission enable. The results show that the system has the advantage of
