Using a SitePlayer SP1 module, it is possible to control four optoisolated inputs and four relay outputs through an Internet web page.

The usage of this module is recommended for industrial and home automation. SitePlayer module is a web server which, as soon as it is connected to the Internet or to an intranet, is able to answer the requests coming from any browser. It answers these requests by sending web pages using the HTML protocol. Web pages of the SitePlayer are dynamic and their parameters can be modified from an external electronic circuit such as a microcontroller connected to a serial port. These parameters can be also modified by commands received from a browser. Finally, it is possible to design an electronic circuit, with digital and analog inputs, digital output and etc., capable of being managed by an Internet web page. For programming the SitePlayer module, first of all, the developer has to design the HTML page. He can choose to write it or to use tools such as Frontpage or Dreamweaver. Then, some scripts connecting the electronic circuit and the web page must be written in a .sdp file. At the end, SitePlayer Linker software merges the HTML and the .spd files into a binary file. This binary file can be uploaded on the web server module. This project, through the usage of the SitePlayer SP1 module, allows managing four digital outputs and four digital opto-isolated inputs through a web page. Using a browser, it is possible to check graphically the status of inputs and outputs. It can work in a Local Area Network (LAN) or in a Wide Area Network (WAN) such as Internet. This module can be used for industrial and home automation in applications like: lighting control, machinery control and heating-cooling plant control.

This project comes in kit. The components have to be soldered to the included PCB.
