DS1820 digital thermometer is used to measure environmen-
tal temperature, having the temperature range of -55°C to
125°C and the accuracy of +/-0.5°C. It must be placed correct-
ly in 3-pin socket provided on dsPICPRO3, with its rounded
side to the left, as marked on the board (Fig 11). Otherwise
DS1820 could be permanently damaged.Switch 4 on SW2
switch group is used to enable DS1820 by connecting it to
microcontroller RF6 pin .
