Abstract: Against the technology of seat statistics (attendance statistics) system on the market is not relatively mature and of wide application, this paper presents a new application direction based on ZigBee wireless data collection technology. Wireless sensor networks technology is applied in this system to construct a seat information statistics system which consists of many wireless sensor nodes and a center node. By combining sensor technology, microprocessor technology and wireless communication technology, the system can realize the functions of pressure signal’s acquisition, fusion and transmission. This system has the advantages of simple operation, especially in public transportation, subway, study room, lecture hall, library, stadiums and other public occasions and has broad application prospect.

Key words: attendance statistics, ZigBee wireless data acquisition, ZigBee streamlined protocol stack, wireless sensor network, CC2430
