The technical characteristics of the ZigBee networks and types of wireless sensor networks are introduced. Three modes of information-based restaurant management are expounded and the design of the order-meal restaurants system based on ZigBee wireless sensor network is proposed. The concrete management model is given in the proposal and the design of software and hardware is realized. Simultaneously, the processes of the ZigBee Networking is elaborated on. The experimental results show that the function of the ZigBee Networking and data communication is realized. The system has the advantages of low power, low price, and wirelessly designed, with far communication distance.
