SparkFun One Wire Digital Temperature Sensor - DS18B20

DS18B20 Maxim/Dallas Semi digital thermometer provides 9-bit to 12-bit Celsius temperature measurements and has an alarm function with nonvolatile user- programmable upper and lower trigger points. The DS18B20 communicates over a 1-Wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor. It has an operating temperature range of -55°C to +125°C and is accurate to ±0.5°C over the range of -10°C to +85°C. In addition, the DS18B20 can derive power directly from the data line ("parasite power"), eliminating the need for an external power supply.

  • Unique 1-Wire Interface Requires Only One Port Pin for Communication
  • Each Device Has A Unique 64-Bit Serial Code Stored In An On-Board Rom
  • Requires No External Components
  • Thermometer Resolution is User Selectable from 9 to 12 Bits
  • Software Compatible with the DS1822
