Adafruit Waterproof 1-Wire DS18B20 Digital Temperature Sensor

Key Features Stainless steel tube 6mm diameter by 30mm long Cable is 36" long / 91cm, 4mm diameter Contains DS18B20 temperature sensor 9 to 12 bit selectable resolution Unique 64 bit ID burned into chip This is a pre-wired and waterproofed (with heat shrink) version of a 1 Wire DS18B20 sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C. Because they are digital, you don't get any signal degradation even over long distances! These 1-wire digital temperature sensors are fairly precise (±0.5°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analog converter. They work great with any microcontroller using a single digital pin, and you can even connect multiple ones to the same pin, each one has a unique 64-bit ID burned in at the factory to differentiate them. Usable with 3.0-5.0V systems.Item SpecificsMultiple sensors can share one pin±0.5degC Accuracy from -10degC to +85degCTemperature-limit alarm systemQuery time is less than 750msUsable with 3.0V to 5.5V power/dataUses 1-Wire interface- requires only one digital pin for communicationUsable temperature range: -55 to 125degC (-67degF to +257degF)
