According to the demands of modern farming intelligentization,vegetable greenhouse environment monitoring sys⁃tem based on ZigBee technology was designed. Through the design of sensor node,coordinator node and router node,as well as terminal controller hardware and software,the wireless monitoring and control of the soil and air humiture,CO2 concentration and light intensity in greenhouse were realized in combination with ZigBee sensor technology. The system overcame the difficult wiring,poor node mobility and poor system scalability in the traditional vegetable greenhouses management,and met the need of automatic monitoring of vegetable greenhouses environmental parameters. Therefore,it is worth being promoted.%根据现代农业种植智能化的需要，设计一种基于ZigBee技术的蔬菜大棚环境监控系统。通过对传感器节点、协调器节点、路由器节点和终端控制器的硬件和软件设计，结合ZigBee传感技术实现了对棚内空气土壤温湿度、CO2浓度和光照强度等参数的无线监测和控制。该系统很好地解决了传统蔬菜大棚管理中布线难、节点移动性差和系统可扩展性差等问题，满足了蔬菜大棚中环境参数自动监测的需要，具有很强的应用推广价值。
