Buy a real thermometer, and an el-cheapo USB webcam. Put the
thermometer in your server room and have the webcam snaps an image of
it every few minutes and make it available through apache or
something.
Reading the temperature values from the images could be done through
some image processing (for alarm purposes in case it's getting hot in
the server room).
