DescriptionThis is a DS18B20 Water Proof Temperature Sensor Probe with Original DS18B20 Chip.One of the easiest and inexpensive way to add temperature sensing in your Arduino project is to use DS18B20 1-Wire Temperature Sensor. These sensors are fairly precise and needs no external components to work. So, with just a few connections and some Arduino code you’ll be sensing temperature in no time!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.The DS18B20 sensor can be powered with a 3V to 5.5V power supply and consumes only 1mA during active temperature conversions.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. When using with microcontroller put a 4.7k resistor to sensing pin, which is required as a pull-up from the DATA to VCC lineSpecificationsPower Supply3V to 5.5VCurrent Consumption1mATemperature Range-55 to 125°CAccuracy±0.5°CResolution9 to 12 bit (selectable)Conversion Time< 750msNote: The probe wire length may vary ±3%
