5.00 JD

This is a waterproof version of the DS18B20 temperature sensor. It provides 9 to 12-bit (configurable) temperature readings over a 1-Wire interface, so that only one wire (and ground) needs to be connected to a central microprocessor. It can measure temperatures from -55℃ to 125℃ (-67F to 257F). In addition, this thermo probe doesn't require any external power supply since it draws power from data line. And its stainless steel probe head makes it suitable for any wet or harsh environment. 

Each DS18B20 sensor contains a unique silicon serial number, so multiple sensors can use the same wire bus. Sensors can be installed in many different places. For example, HVAC environmental control, sensing temperatures inside buildings, equipment or machinery, and process monitoring and control.
