Literature review of an automatic heat detector,block diagram of automatic heat detector

 

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

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

John

 

Temperature is how almost everyone measures delta heat.

Ken

 

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

 

My dog can detect other dogs in heat.

 

My dog can detect poor students. QUIET FIDO!

 

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.

 

Hello,

Even a PIR detector (also called motion detector) reacts on "heat" changes.
Here is a page from the EDUCYPEDIA with a lot of links on Temperature Measurement circuits:

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.

 

As long as there is no further refinement of the term, let me suggest pit vipers - http://www.kidzone.ws/lw/snakes/facts11.htm
