MAX6675 Thermocouple
This project will make use of the MAX6675 Cold-Junction-Compensated K-Thermocouple-to-Digital Converter. It basically takes the millivolts produced by a standard K-type thermocouple, amplifies it, and outputs it’s temperature reading. This reading is received by a microcontroller, which then displays the reading on an LCD display. This unit will be capable of reading temperatures up 1800 degrees fahrenheit.
As you can see the author of this project also used adapters for smd parts. Myself i like to work directly with SMD parts, but sometimes it’s just not possible, especially when prototyping because you always have to tweak something.

I didn’t see any info on the microcontroller or TC? Did you have to program the PIC microcontroller? What type/size of TC did you use?
Thanks,
Tim

Tim, it doesn’t matter which microcontroller you use, you will certainly have to program it. The author doesn’t five much info on the TC used but from the pictures it looks like one you get with your multimeter.

Florin,
Thanks for the feedback. A couple follow-up questions for you. I have never programmed a microcontroller. What software and/or hardware is required to accomplish this? Would I have to buy a special “socket board” to hook the controller up to a computer, and, what about software? Does it generally come with the microcontroller?
Thanks,
Tim

Every microcontroller manufacturer has its own development tools(programmers/debuggers). Almost all microcontrollerul have a so called feature ” in system programming ” where you bring a number of pins to a pin header on your pcb and there you connect your programmer/debugger. If you would like to start with microcontrollers, by far the most easy path is with Arduino. Google it.

Thanks….I will certainly look into it!
