The wireless sensor network (WSN) is one of the most significant technologies in the 21st century. As an open and global standard for WSN, ZigBee shows advantages on low-cost, low power consumption and self-forming. The current researches of ZigBee wireless sensor network on industrial automation, electronic products, smart buildings and medical care were presented and, as an explorative application of ZigBee wireless sensor network in protected agriculture overcoming the limits of wire connection, its applied design for greenhouse management was proposed by introducing both the hardware and software architectures. The node power consumption was also discussed. Finally, the architecture of ZigBee-based mesh network greenhouse management was indicated.
