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. **Documents:** * [Datasheet](http://cdn.sparkfun.com/datasheets/Sensors/Temp/DS18B20.pdf) (DS18B20) * [Simple Sketch Code](https://github.com/sparkfun/simple_sketches/tree/master/DS18B20) * [mbed Example](http://mbed.org/users/snatch59/notebook/onewirecrc/) **Videos**
