This is a waterproofed version of the DS18B20 Temperature sensor which is very handy 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 it’s suggested keeping under 100°C. Because they are digital, you don't get any signal degradation even over long distances! The DS18B20 provides 9 to 12-bit (configurable) temperature readings, so that only one wire (and ground) needs to be connected from a central microprocessor. It’s usable with 3.0-5.5V systems.


Because each DS18B20 contains a unique silicon serial number, multiple DS18B20s can exist on the same 1-Wire bus. This allows for placing temperature sensors in many different places. Applications where this feature is useful include HVAC environmental controls, sensing temperatures inside buildings, equipment or machinery, and process monitoring and control.
