Abstract: In this paper, a design of smart greenhouse remote monitoring system was proposed based on web server and ZigBee technology. By which CC2530 microcontroller was employed for operating ZigBee-stack system and routers which brushed with Openwrt, the network and extranet of the gateway of greenhouse were realized. ZigBee terminals contains two kinds, one consists of temperature and humidity, light intensity, the concentration of carbon dioxide sensors, and the other has a series of control nodes such as ventilation window, blanket, drip irrigation, fill device on-off relay control nodes. Through ZigBee and the gateway, the collected datum was uploaded to the cloud web server network , which provides the man-machine interface. Users can realize the automatic and manual monitor-control through various browsers. The field wiring is not needed in this system. And the collection point is flexible in wide areas. It is conducive to the upgrading of traditional greenhouse to the digital and precision.

Key words: ZigBee, greenhouse, cloud web server
