I am an ecologist studying impacts of climate change on biodiversity. Measuring climate variables in remote locations is a major challenge in my work. Arduino looks like it has great potential as a flexible, modular control system for remote logging applications.
There has been previous discussion of this sort of application on the forum: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1265391221
And some research applications are out there: http://www.stroudcenter.org/research/projects/czo/arduino.shtm
But there is room for more development, especially in flexibility, robustness, and data access. I am very new to the Arduino community, but I am interested to make contact with people who would like to be involved in developing some of these ideas further? I have placed some further info about what I have in mind here on my blog. : http://rainforestbird.wordpress.com/open-source-logger-project/
