I am relatively new to using Arduino. I am looking for anyone with experience using arduino basically as a datalogger for the various analog/digital I/O. I am trying to design a small scale anaerobic digestion / solar hybrid system (off-grid) using arduino as the brains. The end goal is to provide a web interface where a user could view historic trends of the various process parameters and make changes to system operation inside same GUI. I am thinking of using MySQL, Apache Web Server on Ubuntu, Processing, and Arduino together to accomplish this. I am unsure of how exactly these things would work together.
Maybe the MySQL database is unnecessary and everything could be stored on the SD card of the ethernet shield? I am inexperienced in the web-server aspect of this task and I am looking for a little guidance or recommendation.
