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.Dimensions:Probe is 6mm in diameter and roughly 52mm long. Overall length (including wire) is 1m.This version includes a handy adapter board that adds the required 4.7K resistor to connect directly to a microcontroller.Features:3.0-5.5V input voltageWaterproof-55C to+125C temperature range0.5C accuracy from -10C to +85C1 Wire interfaceDocuments:Datasheet(DS18B20)mbed ExampleBildr Tutorial
