Detailed Description

Weathergraphs version 1.1

Copyright 2004 by Kenneth Lavrsen

This program is published under the GNU public license version 2.0 or later.

Attached Files

This is the first ever related project and as an exception it is hosted at Sourceforge.


These program assumes that you have the open2300 software installed for your WS2300 weather station.

You need a webserver with a recent version of PHP including graphical library GD.

A cronjob must fetch data from the station for example every 10 minutes

In /etc/crontab add this line (assuming that log2300 is installed in /usr/local/bin)

0-59/10 * * * * root /usr/local/bin/log2300 /usr/local/apache2/htdocs/weather_log.log

This adds a line of data to /usr/local/apache2/htdocs/weather_log.log every 10 minutes. Make sure that the file is world readable.

Place all the files from this package in a directory on your web server.

Edit all the .php files so that the line..

$fil=fopen("/usr/local/apache2/htdocs/weather_log.log","r"); changed to the real place where you have your weather_log.log file.

That should be it.

Have fun.

Comments and Bug Reports

The code should be defunctionalized. I suggest to have one single class that generates all diagrams. Also a config file should be supported.

I have started working on that. Still I have problems with GD frown, sad smile

I'd suggest, if anyone ever gets round to developing a config file, some way to switch the wind speed graph between m/h, km/h, and m/s. in the meantime does anyone have any ideas how it could be achived easily.
