Hi Tero,
So I have picked up a problem using the DS18B20 as a temperature sensor on the the cylinders of a gas engine, these components only go to 125deg and the engines usually run around 125deg-170deg. This means it's not functional for measuring engine temps. As discussed previously it would be good if we could look at updating the code to use a thermistor, which supports over 200deg. It would be cool if you could take a look, I am going to look into your code, but my knowledge of Arduino is not great.
EDIT: I also noted in your design the resistor on points 3&4 is a 4K and not 2.4K ? is that correct ?
The picture show's 4K but the build asks for 2.4K
regards
Rolf
