6.0. DS1820 temperature sensor

1-wire® serial communication enables data to be transferred over one single communication line, while the process

itself is under control of the master microcontroller. The advantage of this communication is that only one microcontroller

pin is used. All slaveGHYLFHVKDYHDXQLTXH,'FRGHZKLFKHQDEOHVWKHmaster device to easily identify all devices

sharing the same communication bus.

DS1820 is a temperature sensor that uses 1-wire communication for its operation. It is used to measure temperature in

a range between -55 and 125°C and provides ±0.5°C accuracy for temperatures in a range between -10 and 85°C. The

power supply voltage of 3V to 5.5V is used for the operation of this sensor. It takes maximum 750ms for the DS1820

to convert temperature with 9-bit resolution. There is a socket for this temperature sensor provided on the BIG8051

development system. Communication between this module and the microcontroller is enabled via the microcontroller

pin P2.7. To establish communication between them, it is also necessary to set switch 8 on the DIP switch SW15 to

the ON position.
