Hello Alain,

the purpose of this circuit is first to learn
Then it will be for reading temperatures between 20 and 130ºC.

The forum mentioned the LM335 as the best choice but this one does not reach above 100ºC.

I had the LM35 and the LM135 ( which does accept temps higher than 100ºC ) on my list.

The problem is than my local store does not have the LM135 so i'm kinda stuck with this one !

I will retry to write the code with your tip :

" temp = val*125
temp = temp.highbyte "


.
