The DS1820 digital thermometer is
well suited to environmental tempera-
ture measurement, having a tempera-
ture range of -55C to 125C and an
accuracy of +/-0.5C. It must be placed
correctly in the 3-pin socket provided
on the dsPICPRO, with its rounded side
to the bottom, as marked on the board.
Otherwise the DS1820 could be perma-
nently damaged. In order to work,
DS1820 must be connected to micro-
controller’s RD6 pin, by enabling
switch 1 on
