    Hello all.
    In regards to the posts about the DS18B20 sensors and resolution.
    This seems to be a fairly common problem with these sensors.
    I have trouble with this also. How can the resolution be set
    in the DS18B20?

    Hope this is not considered "Thread-Jacking".
    Thanks in advance All.

    You can change the resolution by issuing the read scratchpad command 4Eh
    followed by three bytes. TH, TL, and config. The DS18B20 data sheet explains
    how it works & what values to use for config for various temp resolutions.
    Regards,

    Just remember -- this still doesn't make it a DS18S20, DS1820, or any other
    similar version.
