environmental temperature measurement,
having the temperature range of -55C to 125C
and the accuracy of +/-0.5C. It must be placed
correctly in the 3-pin socket provided on

as marked on the board (see Fig. 42) other-

aged. DS1820’s data pin can be connected to
either RA5 or RE2 pin, which is determined
by jumper JP11.
