Here's the online log and graph of my Arduino-based sensor in New York City:

There are several excellent Arduino tutorials that the Pachube folks have posted - http://community.pachube.com/?q=node/9
I've written a tutorial on my setup, which is posted to the site of the designer of the Danger Shield - http://www.zachhoeken.com/connecting-to-the-world
Please post to Sensor Networks group if you have other sensor examples.
re: pachube + sensor networks
By John GeraciPachube looks amazingly cool. I'm still in the process of digesting the whole thing. I hope others are looking at it too for ideas.
I hope people are checking out the new Sensor Networks Group too. Seems like there could be lots of promising stuff emerging out of that once it gets going.
