AS MY PROJECT I AM CREATING A THERMOCOUPLE THERMOMETER, I WANT IT YOU READ J TYPE. I HAVE FOUND A COUPLE OF CIRCUITS AND I HAVE AN IDEA TO TRY AND COMBINE THEM, BUT I DON'T KNOW WHERE TO START

I HAVE ATTACHED THE DIAGRAMS I AM THINKING ABOUT TRYING TO COMBINE.
ANY HELP WOULD BE MUCH APPRECIATED

 

You forgot to attach the diagrams...

 

these are the diagrams

 

Hello,

A lot of info on thermocouples can be found in thr links from this page of the EDUCYPEDIA:

Your first attachment is pretty much unreadable.

It looks like you want to replace the BC547 transistor, used as the temperature sensor in the first circuit, with the voltage output, V1, of the second circuit. If that is a ICL7106, then your V1 should go across pins 30 and 21. Check the data sheet for full details.

Is this a school assignment, in which you must use a J type thermocouple? Depending on range your design could be simplified if you use a LM35. Just a tip.
