temperature sensor using DS18B20 HOW TO SET TEMPERATURE USING ATEMGA8 (by 80proof)
HI GUYS! can someone teach me how to set the temperature sensors in degree celsius, my plan is using this DS18B20 sensor at pin 28 of atmega8 if my temperature sensor has reached already the 40 degrees celsius the pin 25 will output a logic 1 which will trigger a relay that will power on a 5v dc motor fan. and if i got higher value than 40 the other pin 24 will again generate a relay and will turn on again the other fan..can someone help me with this problem? thanks!! hoping for your reply guys!!

You could instead use an analog temperature sensor, as in

Hi, this post is from over 10yrs ago now, has LDmicro been updated with 1-wire bus capability now?

No and there's not even a chance that this will happen in the future.

There is no one left who can develop LDmicro further and you cannot fulfill all wishes as a developer.

Yes it's a shame because there are still some bugs in the current version that need a fix.
