The WPSE324 ( DS18B20) Digital Thermometer provides 9 to 12-bit (configurable) temperature readings which indicate the temperature of the device.
Features:

1. DS18B20 specs: unique 1-wire interface requires only one port pin for communication
2. multidrop capability simplifies distributed temperature sensing applications
3. requires no external components
4. can be powered from data line, power supply range is 3.0 V to 5.5 V
5. zero standby power required
6. measures temperatures from -55°C to +125°C (Fahrenheit equivalent -67°F to +257°F)
7. ± 0.5°C accuracy from -10°C to +85°C
8. thermometer resolution is programmable from 9 to 12 bits
9. converts 12-bit temperature to digital word in 750 ms (max.)
10. user-definable, non-volatile temperature alarm settings
11. alarm search command identifies and addresses devices whose temperature is outside of programmed limits (temperature alarm condition)
12. 3-wire adaptor for Arduino included
