I recently purchased a wood stove that has a temperature sensor on it for the operation of the catalyst. The sensor plugs into a little LCD display via a k-type thermocouple plug.

The LCD provided with the stove powers off after about 15 minutes, since it's only running off a 9V battery. I wanted something like a picture frame on the mantle displaying the temperature all the time.
