AJ,
You may want to investigate temperature buttons. This link is for a full system http://www3.sympatico.ca/photologic/dr.htm
The temperature ibutton http://www.ibutton.com/ibuttons/index.html seem to sell individual parts with a temperature ibutton sensor starting at $2.23. I haven't investigated this very far, but a few years ago was told about them by a fellow bicyclist who like to monitor temperatures on his rides. I am not that fanatical.
If you google temperature + button you will come up with other links to this technology.
