DS18B20 Digital temperature sensor

This is the latest DS18B20 1-Wire digital temperature sensor from Maxim IC. Reports degrees C with 9 to 12-bit precision, -55C to 125C (+/-0.5C). Each sensor has a unique 64-Bit Serial number etched into it – allows for a huge number of sensors to be used on one data bus. This is a wonderful part that is the corner stone of many data-logging and temperature control projects.

Features: 

• Can be powered from data line. Power supply range is 3.0V to 5.5V
• Requires no external components
• Measures temperatures from -55°C to +125°C (-67°F to +257°F)
• ±0.5°C accuracy from -10°C to +85°C
• Applications include thermostatic controls, industrial systems, consumer products, thermometers, or any thermally sensitive system
