This is a pre-wired and waterproofed (with heat shrink) version of the DS18B20 sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125℃ the cable is jacketed in PVC so we suggest keeping it under 100℃. 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℃ over much of the range) and can give up to 12 bits of 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.



Not for use in salt water or other corrosive environments. These are not IP rated, and are not guaranteed for long term/high pressure usage.
