Home-brew enthusiast Justin had completed a Fermentation Temperature controller for his brewing setup, and then went further and built an Internet-based information display showing various parameters from DS18B20 temperature sensors. Here is an example screenshot from the resulting code:
Although you may not be interested in home-brewing alcohol, the project is interesting in that you can adapt it to display parameters from your own project over the Internet. So for more information, Arduino and Python code visit Justin's project page here. And we're on twitter, so follow us for news and product updates as well.
To replicate your own Arduino-Internet information system, a great start is the Freetronics EtherTen. Apart from being fully Arduino Uno-compatible, it has onboard Ethernet, microSD socket and supports optional Power-over-Ethernet:
