An ZigBee wireless network monitor system for intelligent agriculture application was proposed. Aiming at fine measurement and control, automatical management,product traceability, a mutillayer wireless sensor network structure was suggested. Hardware system design based on TI SOC chip and the topological structure were discussed. Experiment results show that the proposed mesh network has the features of strong selfhealing ability, high stability and big capacity. It provides reference for the research and practice in wireless network intelligent agriculture system.
