New MCP690X Thermocouple Component.

[medelec35]

I have just created a new MCP960X Thermocouple Component.
It has now been pushed onto the update system, so you will need to run an update (Help, Library updates) and change Files in-use to full database.
You will find the component in Sensors, Environmental or just use the search and enter 960
This component is ideal if you need to measure a temperature using the following types of thermocouples:
K, J, T, N, S, E, B and R
Compatible devices are MCP9600 & MCP9601.
The latter only has open and short circuit indication if that is required?
If you don't want to solder the thermocouple IC onto a PCB, then you purchase a breakout board.
The one which I'm using is the Sparkfun Qwiic Thermocouple Amplifier - MCP9600 (Screw Terminals) from COOL COMPONENTS.

Although the breakout board has 3V3 marked on it, the component will happily run at 5V.
The reason for indicating 3V3 is you can connect other Sparkfun boards which could only run at 3V3!
So, if just using the single board you know 5V will be fine.
The board communicates with the Microcontroller via I2C, so only two connections are involved.
You can have more than one MCP9600/1 connected of course.
See this Post below for details on how to download a demo Flowchart.
For the display, I'm using is LCD 4 x 20 I2C backpack that can be connected to the same two pins as thermocouple IC.

Hi Martin!

Thank´s for the new component. Maybe stupid question, what is the ref doing, is it to adjust offset for different element?

Thank´s

Hi Jorgen,
Your welcome & thank you for your interest.
Ref or Reference Temperature is the actual temperature of the IC itself.
So If you put your finger on the IC, you will notice the Ref temperature increasing.
Note: Some datasheets call the reference temperature the cold temperature.

Hi Jorgen.

I believe the ref temperature is a sensor on board the thermocouple ic which allows for cold junction compensation and allows for more accuracy of the thermocouple temperature reading. It's all done for you but sometimes the ref reading is useful to have to monitor the internal temp of the electronics.

Lol Martin beat me to it

Thanks, Ben.
Its always better to have 2 answers than none
I would also like to add, the component itself also mentions the Ref temperature:

Hi both!

Yes I will order some.

And Martin wrote : "Its always better to have 2 answers than none " ablsolutely, and further more from some of the best

Thank´s for reply. And now I dare to say, Hope Denmark win the football match.

It was looking like you might for a while there.

Hi, Jorgen.
I have just added a demo file to the wiki.
The best way to access the file is within Flowcode.
If the component is not added to the 2D panel, select the component from the Sensors (or use Search ).
Right-click on the component and select Help:

Scroll down the wiki page that has just opened within Flowcode to Examples:

If the component is already on the 2 panel. then you can right click it and select help.

WOW Martin!

Thank you. As soon I receive one I will test it and you hear, maybe some more question
