Connecting Embedded Systems To The Internet

This paper deals with a proof-of-concept project that will demonstrate how sensor data can be retrieved over data networks. The project also tries to achieve this goal in a cost sensitive manner by utilizing open source software and low cost hardware. The concept is to provide environmental temperature sensing at a remote site and regularly update a web page with this temperature. The display of the data is controlled remotely through a web browser with the data returned to the browser. Commercial implementations of this technology are available today from a number of different vendors including EmWare and Picoweb. These commercial products provide Internet connection to devices for obtaining data and providing control through a web browser.
