Description :

– This sealed digital temperature probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface.
-The DS18B20 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.
-Note: The pinout for this sensor is as follows: RED=Vcc BLACK=GND WHITE=SIG

–Features:

•3.0-5.5V input voltage
•Waterproof
•-55°C to+125°C temperature range
•±0.5°C accuracy from -10°C to +85°C
•1 Wire interface
•Probe is 7mm in diameter and roughly 26mm long. Overall length (including wire) is 6 feet.
