I will create a digital thermometer with a (-) Measuring limits. probably around -20.
I've got atmega8535, lm335, and ds18s20.
Can someone help me? Thanx,.

because LM35 less accurate at temperatures below 0 degrees celcius

I just don't understand this. you are planning to do something that you clearly have no clue about.

that doesn't sound very rationale, does it?

why don't you guys start to plan on things you do know something about? that way, you can actually make some progress.
