DS18B20 -1 Wire Digital Temperature Sensor
Product Images shown are for illustrative purposes only and may differ from the actual Product. Due to differences in PCB manufacturers, colours, pin mappings, markings & packaging of products/PCBs may also differ from those shown above.

DS18B20is 1-wire digital temperature sensor from Maxim IC suitable with 9 to12 bit precision over the range of operation (-55°C to 125°C) .

With an accuracy of ±0.5°C over the range of -10°C to +85° and multiple data logging of temperature spread in wide area network, connected in single data bus, DS18B20 comes handy as it has been assigned unique 64-Bit Serial Number, thus a single microcontroller can receive data from many DS18B20s distributed over a large area. 


  • 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 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

  • 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
