Abstract:  In order to solve the limit problems of wired deployment about informationmonitored system in the hotel room, the wireless sensor network technology based on ZigBee 2007/PRO protocol for the refrigerator billingmanagement system was investigated. Based on the introduction of ZigBee technology, the entire system framework was designed, the software and the hardware designs of the system were introduced in detail, and  the function that the hotel foreground intensively managed information in every room was achieved. The study results show that, the scheme eliminates the limitation which the traditional network cabling brings, and has the characters, such as wireless transmission, convenient maintenance, lowcost, high reliability and low bit error rate.
Key words: ZigBee 2007/PRO protocol stack; wireless sensor network; goodsbilling system in refrigerator
