Abstract：The indoor three-level wireless sensor network system was constructed to realize the low latency and highly effective wireless control of the greenhouse environment information.Head node for remote and short distance wireless communication was designed,which was one of the key elements of network system.The cluster head node was made up of short wireless communication module CC2430 and global system of mobile communication GPRS module.The wireless transceiver program based on the Zigbee protocol and the GSM network transmission program based on the embedded TCP/IP protocol were designed.The results of the network system experiments show that the greenhouse environment physical quantities such as temperature can be obtained momentarily,and the system has lower cost,lower latency and quicker response compared with the general wireless sensor network.Efficient and wireless information communication between the wireless sensor node and remote management computer is realized.
