In reply to Sara Santos. Absolutely, I am using one currently, just put it together today actually. It reads temperature from my wood stove. It also displays it on a SSD OLED . Currently monitoring my output temperature and soon I it will control fan on off to eliminate cold air output. Thanks to your team for the instructions and inspirations.

How can I have temperature below 0 measured and presented. Now the measurement stops at 0. So a temperature below 0 is not presented

How long does it take to detect and instantaneous 50 degrees celsius difference?

In reply to Sara Santos.

Looks like there is a MAX 31855R for R type. But not widely available (looking on US eBay). One from India — https://roboindia.com/store/max-31855-r-type-module-thermocouple — pretty sure there are lots of examples on interfacing to the 31855R — so easy to modify one of your projects.

Sorry, I am just a beginner on this, but is there not a mistake in this line

int thermoDO = 12;
int thermoCS = 15;
int thermoCLK = 14;

In reply to Dave F.. Got it to compile -- just declared a string "s" and a float "tempC" and then --

  tempC =  thermocouple.readCelsius();
  publisher("test_out/thermo", s+"Read (C):  "+tempC);
