    Like this? Maybe a little more detail on your class assignment (?)!

    "Typical engineer." The OP asks for heat, and you give him temperature. :D

    Temperature is how almost everyone measures delta heat. ;)

    Fingertips. If owner of finger screams, either heat or extreme lack of heat (cold) is detected.

    My dog can detect other dogs in heat.

    I guess that by now you realise that a little more information would be helpfull for your "temperature" measurement or detection. Some common sensors are: bi-metal, mercury thermal expansion; thermistors, diodes- resistance change with temp.; thermacouples - self voltage production porportional to temp.

    After reading your post, and re-reading the OP, with some interpretation and lack of coffee, that might be what he is asking for.

    I guess we will find out when he returns.

    Not anyone that has learned thermodynamics. Set a pot to boil on the stove. It'll start boiling at 100C, but you'll still have to add a LOT of heat to boil it all away. Lots of delta H with zero delta T. But perhaps this detail is irrelevant to the OP, who appears to have left us.
