• Usable with 3.0V to 5.5V power/data
• Stainless steel tube 6mm diameter by 35mm long
• ±0.5°C Accuracy from -10°C to 85°C
• Uses 1-Wire interface- requires only one digital pin for communication
• Comes with a resistor module so it is easy to connect on the Arduino board

The DS18B20 Waterproof Digital Temperature Sensor Kit provides 9 to 12-bit (configurable) temperature readings over a 1-Wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor. Compatible with 3.0-5.5V systems.
