Just a concept at this point, but I'd like to try out something like this as an RF transmitter / receiver: http://www.sparkfun.com/products/10535 http://www.sparkfun.com/products/10533 Perhaps be able to make sub $20 sensor / transmitters that would send temperature information back to a base unit with the cell phone connection. I am setting up a new farming area where I would have 8 to 10 mini tunnels. Some might be covered in plastic, some might not. It would be critical in the spring to know how hot it is in each of them.

I don't have much to add since my Arduino has not even arrived yet, but sounds like we are pushing it to the limit which is pretty exciting.
