This is a waterproofed version of the DS18B20 Temperature sensor for Arduino. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125 degree, the cable is jacketed in PVC keeping it under 100 degree Celsius. This sensor 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.Usable with 3.0-5.5V systems.Specification: 1.Cable length: 100 cm2.The probe the temperature sensor DS18B20 original chip3.High quality stainless steel tube encapsulation waterproof moisture proof to prevent rust.4.Stainless steel shell 6*50mm5.Power supply range: 3.0V to 5.5V 6.Operating temperature range: -55°C to 125°C (-67°F to 257°F) 7.Storage temperature range: -55°C to 125°C (-67°F to 257°F) 8.Accuracy over the range of -10°C to 85°C: ±0.5°C. 9.No other components, unique single bus interface
