The temperature values are meaningless. How to accumulate that info? #2

When the code is executed, the temperature values are around 450 to 600. How do I change it in order to obtain Celcius degrees?

I don't really remember this but you should find the resolution of the ds18b20 in the data sheet. I'm pretty sure it's in celsius already though.

Are you running this in room temperature? You have a very large variation, so unless you are changing the temperature my guess is that you're not reading it properly from the ds18b20...

Hello, thanks for the fast reply.

I have to say after shifting through a precision of 9 bits , I got the right results. I would like to contribute to that part when I have time.

There's now a float member representing the actual temperature
