IP68 Waterproof Ds18b20 Digital Temperature Sensor
Description:
Digital temperature sensor DS18B20 waterproof employs DALLAS DS18B20. Its unique 1-wire interface makes it easy to communicate with devices. It can converts temperature to a 12-bit digital word in 750ms (max). Besides, it can measures temperatures from -55° C to +125° C(-67F to +257F). In addition, this thermo probe doesn't require any external power supply since it draws power from data line. Last but not least, like other common thermo probe, its stainless steel probe head makes it suitable for any wet or harsh environment.
Application:
The digital sensor provides 9 to 12 bit (configurable) temperature readings which indicate the temperature of the device. Information is sent to/from the DS18B20 over a 1-wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor to a DS18B20. Power for reading, writing, and performing temperature conversions can be derived from the data line itself with no need for an external power source.
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.
