14.0. DS1820 Temperature Sensor
1-wire® serial communication enables data to be transferred over a single communication line while the process itself is under control of
the master device. The advantage of such communication is that only one microcontroller pin is used. All slave devices have by default a
unique ID code, which enables the master device to easily identify all devices sharing the same communication interface.
The DS1820 is a temperature sensor that uses 1-wire communication for its operation. 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 5.5V is required for its operation. It takes maximum 750ms for the DS1820 to calculate temperature with 9-bit resolution. The
LV 18F v6 development system provides a separate socket for the DS1820. It uses either RD0 or RA5 pin for communication with the
microcontroller, which depends on the position of jumper J11. In Figure 14-5, jumper J11 is placed in the RD0 position, which means
that 1-wire communication is enabled via the RD0 microcontroller pin.
