Abstract： With the rapidly development of wireless sensor network， it has become a hot spot in the research of wireless sensor network to access embedded system into internet， and one of the technical difficulties is to realize the dynamic display of the collected data through accessing the Web in the embedded operating system. Using temperature sensor DS18B20 to collect the temperature data， and then ARM-Linux is constructed in the embedded gateway. BOA server is migrated while the CGI program， Ajax technique and Html language are used to realize real-time displaying the data in the Web page. The actual application shows that the system consumes less CPU resources， which can reduce the burden of the server， and need not to update the data， thus the waiting time for users in practical application is reduced.
