General Description

GND - Ground DQ - Data In/Out VDD - Power Supply Voltage NC - No Connect DESCRIPTION The DS18B20 Digital Thermometer 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.
