The DS18B20 is a well-adopted temperature sensor that features the 1-wire protocol. SeeedStudios has prepared the sensor into a tidy probe with a 2M (6.6′) long waterproof cable.

The original one includes three wires inside. You need to add an extra resistance to get it working. We adjusted it into a Grove port and had a resistance pre-assembled inside so that you can use it as a regular Grove sensor.


  • 6mm diameter probe, 31mm long
  • -55 to +125°C (-67 to +257°C) to temperature measurement range (probe only – keep wire immersion under 70°C)
  • High accuracy: ±0.5°C (-10 to +85°C)


  • Requires only one wire for data interface
  • Waterproof
  • Grove compatible
  • 3.0V to 5.5V power supply


NOTE: The cable portion cannot be put under temperature higher than 70°C for a long time.
