I modified it a liitle bit: http://www.opensketches.org/en/temperatur-messen-mit-einem-lm35-und-anzeige-auf-einem-lcd-display-processing-anzeige-mysql/
Now the temperature will be shown in a processing sketch and processing inserts the data in a mysql database. You will need a serial connection.

I'd like to send the values via bluetooth to a smartphone, which will store the values in a database.
