Popular both in industry, and in the hobbyist/maker community; the Dallas/Maxim DS18B20+ digital temperature sensor offers unparalleled versatility in temperature sensing and control, making it ideal in applications as varied as 3D-Printing, Sous-vide cooking and whole-home thermal management.

Product Description

The DS18B20 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.


Features:
  • Arduino sketch and library support.
  • 1-wire interface requires only one pin (+ Ground) for communication
  • Each device has a unique 64-bit serial code stored in an on-board rom
  • Multidrop capability simplifies distributed temperature-sensing applications
  • Can be powered from data line
  • 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
  • Thermometer resolution is user selectable from 9 to 12 bits
  • ROHS compliant.
