    To answer that I did a quick net search...
    "The DS18S20 is a digital thermometer featuring 0.5C accuracy over a -10C
    to +85C range. Data is read out over a 1-Wire serial bus in 2's complement
    format with 9 bits of resolution."

    So whether it be via software or hardware, some form of serial communication
    interfacing must be implented.

    An article and some C code can be found at: http://www.phanderson.com/PIC/
    Also check out: http://www.bol.ucla.edu/~frank/LCDTemp.htm
    There's lots of info out there on this device!
