10.0. 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 de-
vices 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
EasyAVR6 development system provides a separate socket for the DS1820. It may use either PA4 or PB2 pin for communication
with the microcontroller. Jumper J9’s purpose is selection of the pin to be used for 1-wire communication. Figure 10-4 shows 1-wire
communication with microcontroller through the PA4 pin.
