uhrbahn:
Can you please give ma a hint on how to print the averaged sensor value to my display instead of printing
to the serial monitor?

Proably something like that:

  ...
  Serial.print("Temperature "); 
  Serial.print(steinhart);
  Serial.println(" *C");


  char valueText[8]; //enough space for "-XXX.XX" + 1 for the null terminator
  dtostrf( steinhart, 1, 2, valueText ); // convert float to char array (with 2 digits precision)
  TFTscreen.text( valueText, 0, 20 );
  ...

Untested, but should work...

And just because the word "dtostrf" doesn't appear colored in the IDE doesn't mean it's not recognized. If it compiles without errors, it is recognized :slight_smile:
