EasyPIC6 Development System
10.0. DS1820 Temperature Sensor
1-wire® serial communication enables data to be transferred over one single communication line while the process itself is under the
control of the master microcontroller. The advantage of such communication is that only one microcontroller pin is used. All
have by default a unique ID code, which enables the master device to easily identify all devices sharing the same interface.
DS1820 is a temperature sensor that uses 1-wire® standard 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. 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 EasyPIC6 development
system provides a separate socket for the DS1820. It may use either RA5 or RE2 pin for communication with the microcontroller. Jumper
J11’s purpose is selection of the pin to be used for 1-wire® communication. Figure 10-5 shows 1-wire® communication with microcontroller
through the RA5 pin.
