The DS18B20 Digital Thermometer provides 9 to 12-bit (configurable) temperature readings whichindicate 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, andperforming temperature conversions can be derived from the data line itself with no need for an externalpower source.Because each DS18B20 contains a unique silicon serial number, mulTIple DS18B20s can exist on thesame 1-Wire bus. This allows for placing temperature sensors in many different places. ApplicaTIonswhere this feature is useful include HVAC environmental controls, sensing temperatures inside buildings,equipment or machinery, and process monitoring and control.
