  • This is a waterproofed version of the DS18B20 Temperature sensor.
  • Handy for when you need to measure something far away, or in wet conditions.
  • While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C.
  • Because they are digital, you don’t get any signal degradation even over long distances.
  • The DS18B20 provides 9 to 12-bit (configurable) temperature readings over a 1-Wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor. Usable with 3.0-5.5V systems.
  • Because each DS18B20 contains a unique silicon serial number, multiple DS18B20s can exist on the same 1-Wire bus.
  • This allows for placing temperature sensors in many different places.
  • Applications where this feature is useful include HVAC environmental controls, sensing temperatures inside buildings, equipment or machinery, and process monitoring and control.


  • Uses 1-Wire interface- requires only one digital pin for communication
  • Unique 64 bit ID burned into chip
  • Multiple sensors can share one pin
  • Temperature-limit alarm system
  • Query time is less than 750ms
  • 3 wires interface:
  • Red wire – VCC
  • Black wire – GND
  • Yellow wire – DATA.
  • Usable with 3.0V to 5.5V power/data
  • +-0.5degree Accuracy from -10degree to +85 degree
  • Usable temperature range: -55 to 125 degree
  • 9 to 12 bit selectable resolution
  • Stainless steel tube 6mm diameter by 50mm long
  • Cable diameter: 4mm
  • Cable Length: 100cm.
