A set of 5 x DS18B20 sensors!
This is a digital temperature sensor that can be used with any Arduino board. It measures temperatures from -55°C to +125°C and outputs a digital signal that can be read using one of the digital pins on the Arduino.
The benefits of this sensor over an Analog one are that it does not occupy an Analog pin on the Arduino (On an UNO there are 6 Analog pins vs. 14 Digital pins), it only requires one wire to communicate, and outputs digital values that correlate with the measured temperature (so no correction tables are required). Also each sensor has its own address so several sensors can be connected to one digital pin allowing you to read the temperature of each sensor separately without using extra digital pins on your Arduino!
