1-wire® serial communication enables data to be transferred over a single communication line while the process itself is under control of
the PDVWHUdevice. The advantage of such communication is that only one microcontroller pin is used. All VODYH devices have by default a
XQLTXH,'FRGHZKLFKHQDEOHVWKHPDVWHU device to easily identify all devices sharing the same communication interface.
The DS1820 is a temperature sensor that uses 1-wire communication. It is capable of measuring temperatures within the range
of -55 to 125°C and provides ±0.5°C accuracy for temperatures within the range of -10 to 85°C. A power supply voltage of 3V to

BIGAVR6 development system provides a separate socket for the DS1820. It uses either PB0 or PG0 pin for communication with the
microcontroller, which depends on the position of switches 1 and 2 on the DIP switch SW14.
