The smart sensor is assigned a unique Internet Protocol (IP) address on a network that is accessible from the workstation. A standard Web browser running on the workstation is used to connect to the smart sensor. There are tabs at the top of the screen that allow access to six different panels (Main, Health, Measurements, Calibration, Configuration, CPU Status). Each of these panels contains fields that are updated in real time using the Web Sockets connection.
HTML5 Web Sockets provided a simple and effective way of updating dynamic Web page content in real time from an embedded device. The protocol developed to address and update fields on the Web page was easy to implement, and can be extended if necessary to handle other types of Web page information.
