Abstract: With the rapid development of information and communication technology, People’s life will happen a lot of progress,Corresponding to the surrounding environment of the demand is higher and higher,Large-scale wireless sensor communication system applications in environmental monitoring will be more and more common. Wireless sensor network is shirt-sleeve the sensor、Embedded computer、wireless communication、Distributed information processing science knowledge,it through the integration of various environmental miniature sensors or test object information detection and acquisition,Again through the wireless network to send to the user. Based on the analysis of the structure of wireless sensor network are put forward,based on the information acquisition of light to wireless sensor network node design,realization of light information collection and ZigBee wireless transmission agreement,forming a tree network to achieve data collection and transmission.
This paper introduces how to use the radio frequency chip CC2530 based on ZigBee wireless data acquisition system with microcomputer. CC2530 single-chip computer and RF chip as the core design of low power wireless data acquisition system,This paper introduces the wireless sensor network (WSN)、ZigBee technology、and presents the composition of wireless data acquisition system based on ZigBee,and finally by using CC2530 chip completed acquisition node,main control unit of hardware and software design and realization of data acquisition and wireless transmission.
