The DS18B20 Digital Thermometer provides 12-bit centigrade 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/microcontroller. 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.


  • Calibrated directly in ° Celsius (Centigrade)
  • Unique 1-wire interface requires only one port pin for communication
  • Each device has a unique 64-bit serial code stored in an onboard ROM
  • Multi-drop capability simplifies distributed temperature sensing applications
  • Requires no external components
  • Can be powered from the data line. The power supply range is 3.0V to 5.5V
  • Measures temperatures from –55°C to +125°C (–67°F to +257°F)
  • ±0.5°C accuracy from –10°C to +85°C
  • 12-bit thermometer resolution
  • Converts temperature in 750 ms (max.)
