Abstract: The greenhouse needs the monitoring of the parameters like temperature, humidity and light. These parameters should be kept within the specified range. All these real-time parameters are measured and sent to coordinator through ZigBee. As an open and global standard for wireless sensor network Zigbee protocol, IEEE 802.15.4 shows advantages on low cost, low power consumption and low data rate. Zigbee‘s network layer supports three networking topologies star, mesh, and cluster tree. Star networks are common and provide for very long battery life operation. Zigbee based wireless monitoring and control system in the greenhouse is composed of a coordinator and end devices including sensor nodes and electrical devices organized as a star network. By running software, the coordinator periodically receives the data from the wireless sensor nodes and displays them on its LCD. Meanwhile, it sends orders to electrical devices in the network to control them automatically.
