Research Of Wireless Sensor Network Based On MSP430

In the last century, along with the rise of Internet technology, people entered theInformation Age. While nowadays as new technology’s growth like Micro ElectroMechanical Systems, System on Chips, Embedded Systems, Distributed InformationProcessing Technology and Artificial Intelligence, here comes the age of “Internet ofthings”. Different from the Information Age, this new technology is established bypeople, but running without people’s care. These physical objects, connecting with eachother, are always working in the same network, communicating with others as wanted.In short, designers make rules, objects obey. People who are enjoying this systemalways are not aware of it, as the theory of “Pervasive Computing”.In order to build the Wireless Sensor Network system, lots of sensor nodes will beplaced in the area people want to supervise, and these sensor nodes are responsible forcollecting the information people want to know. After being analyzed by our system, allthe information will be transmitted by the Wireless Sensor Network to the sink node,which acts as our basement.The purpose of our product is aimed at3C digital retails, with its help, we canabandon the line fixed on the goods, then we users can enjoy the commodity freely. Inthis system, sensor node will be fixed on the goods, collecting real-time data andtransmit them to the sink node, while the sink node will be connected to the PC. Everynode mainly contains three parts: the control unit, data collecting unit and transmittingunit. Data collecting unit is responsible for collecting real-time data throughMMA7455L. After these data are handled and analyzed by the MCU: MSP430, theywill be sent to a sink node through Wireless Transceiver System, in which NRF24L01isused to form this network, SPI protocol is used between them. MCU will build a tasklist, system will detect relative event, then handle the request and react, thus, our systemwill accomplish the requirements of users.
