with automatic control theory as the theoretical basis, application of sensor and actuator to form a closed loop control system. The growth environment of sensor nodes equipped with sensors to plant, control node with actuator control device for improving plant growth environment. Sensor nodes and control nodes cooperate with each other, to provide suitable environment for the growth of the plant.

2 systemThe structure of

system consists of a wireless sensor network,2014 wireless outdoor home security cameras, gateway and the master control center. Wireless sensor network is a network of nerve ending, change is responsible for sensing the environment, and the data to the Internet through gateway. The system architecture is shown in figure 1.

The

ZigBee is a new short-range, low rate wireless network technology [l]. It is built on the IEEE 802.15.4t2I standard,2014 high resolution cctv camera, IEEE provides ZigBee physical layer and media access control layer, network layer,2013 wide angle security camera, application support sublayer and the application of high standards developed by the ZigBee alliance. The ZigBee protocol provides three available frequency band 868MHz,best home security monitoring service, 915MHz and 2.4GHz,2014 outdoor security cameras for home, respectively 1, 10 and 16 A total of 27 channel. The 2.4 GHz for universal frequency, transmission rate of 250 KB / St 31. The overall design of the

Abstract: in view of the traditional manual time-consuming and wired monitoring complex wiring,2013 security camera online, maintenance limitations difficult,2014 pinhole cctv camera, sensor and ZigBee wireless network technology, puts forward the design scheme of Intelligent Greenhouse Monitoring System of wireless sensor networks. This system uses ZigBee technology to realize wireless transceiver to collect data and information, data and control information is transmitted to the Internet through the common gateway interface CGI. The operator can from a distance of
