11.0. DS1820 Temperature Sensor
1-wire
control of the master microcontroller. 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 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 BigPIC6
development system provides a separate socket for the DS1820. It may use either RE2 or RE5 pin for communication with the
microcontroller, which depends on the position of switches 7 and 8 on the DIP switch SW12. In Figure 11-5, switch 8 on the DIP switch
SW12 is in ON position which means that the communication is enabled via the RE5 pin.
