Description

The DS18B20X Digital Thermometer provides 9 to 12-bit (configurable) temperature readings which indicate the temperature of the device.

Information is sent to/from the DS18B20X over a 1-Wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor to a DS18B20X. 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 DS18B20X contains a unique silicon serial number, multiple DS18B20Xs 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.
