Wireless Sensor Networks (WSN) is a large number of distributed, small, specifications and functions of different sensor nodes, through its own sensing, computing and communications capability posed by the network system. It can be integrated dynamic signal acquisition, processing and transmission of information and can automatically adapt to environmental changes, in the case of unattended task independently.In this paper, with the topic of "Research and development for Smart IP wireless sensor control of the ARM-side ", after detailed research and feasibility studies, on the basis of the current in-depth study of the popular theory ,this paper produces a new way to realize it. The use of embedded technology in the ARM processor platform design and development of a wireless embedded sensor, the major work done including:First, on the background of wireless sensor networks, the development of the status, meaning and content of the study, and then combined with the embedded IP sensor theory, discusses the working principle of their model and get ready for actual system design.Next step is the hardware design and realization of the environment. Demand for design, a selection of ARM processor chips, EEPROM, SDRAM, FLASH memory, so that the processor chip and system integration for the smallest. On this basis the completion of the Ethernet port, serial peripheral interface, such as the design and preparation of the driver was successfully integrated with the minimum system constituted in one hardware system. Then, cross-compiler building environment, embedded operating system and file system of the transplant.Finally, based on specific functional requirements for the design of a temperature sensor to prepare software modules. Including wireless communication module, Web Server Embedded Server module, dynamic interactive web pages CGI module, database module, such as embedded part of the main part.After the prototype of the system design and experimental testing indicates that the model is reliable and of the results of tests, to collect and upload accurate temperature data, dynamic web pages to display and refresh. Meet the performance indicators, the better to complete the design requirements.
