I wrote a piece of software which takes the serial connection from the receiving Arduino, and turns it into several charts. It’s just in beta right now, but it can be used as a Arduino to web interface through the use of a MySQL library.
The output of the program to the MySQL table looks something like this…
That same data is used in a simple .php page which echos the latest ids.
And there you have it! An online, real time, weather display!
Next steps include adding more sensors using reed switches, expanding the functionality of the server program, and transferring the electronics over to a perfboard.
