This is the latest DS18B20 1-Wire digital temperature sensor from Maxim IC. Reports degrees C with 9 to 12-bit precision, -55C to 125C (+/-0.5C). Each sensor has a unique 64-Bit Serial number etched into it - allowing for a huge number of sensors to be used on one data bus. This is a wonderful part that is the cornerstone of many data-logging and temperature control projects.

  • 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
  • Multidrop capability simplifies distributed temperature sensing applications
  • Requires no external components
  • Can be powered from a data line. The power supply range is 3.0V to 5.5V
  • Measures temperatures from –55 DegreeC to +125 DegreeC (–67 DegreeF to +257 DegreeF)
  • ±0.5 DegreeC accuracy from –10 DegreeC to +85 DegreeC
  • Thermometer resolution is user-selectable from 9 to 12 bits
  • Converts temperature to 12-bit digital word in 750ms (max.)
  • User-definable nonvolatile (NV) alarm settings
  • Alarm search command identifies and addresses devices whose temperature is outside of programmed limits (temperature alarm condition)
  • Applications include thermostatic controls, industrial systems, consumer products, thermometers, or any thermally sensitive system
