This sealed digital temperature probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface. 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.

Dimensions: Probe is 7mm in diameter and roughly 26mm long. Overall length (including wire) is 6 feet.

  • Waterproof
  • -55°C to+125°C temperature range

  1. Review by Rick verified purchaser

    Great for putting in outdoor applications. (Posted on 10/10/2016)

  2. Review by Will verified purchaser

    Sensor seem to work well. The have a long cable and a short probe length which is what we were looking for. Construction quality seems to be pretty good. I'm logging 9 of these from one Raspberry Pi using telephone cable and connectors/splitters to put it all together. (Posted on 10/06/2016)
