Use an RF transmitter / receiver
Just a concept at this point, but I'd like to try out something like this as an RF transmitter / receiver:

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.
