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.
  • 3.0-5.5V input voltage
  • Waterproof
  • -55 DegreeC to+125 DegreeC temperature range
  • ¬±0.5 DegreeC accuracy from -10 DegreeC to +85 DegreeC
  • 1 Wire interface

DS18B20 Temp sensor

Item works as described, used with STM32, 1 Wire serial fairly easy to implement, just create a consistent microseconds delay function.

Hobby Purchase

The sensor works as described. Make sure to read the datasheet (available on the product page) on how to connect it, you might need a 5k Ohm resistor to power it. It has advanced functions as tmp alarms, resolution settings and you can connect multiple sensors over one cable, which can transfer both data and power - it's fantastic if you ask me. Mine also got shipped almost instantly.

Easy to use

The example given was for an Arduino but it was relatively easy to adapt it for a Particle Photon. I am planning to use it to monitor the temperature in a fish tank. Since it is digital, I do not have to worry about reading fluctuations if the cable is moved around.

Repeat purchase

I bought one of these temperature sensors for an arduino project to monitor the temperature of my hot water tank. I used a 3.5mm stereo jack on the end and a socket on my project box. As the first sensor is now semi-permanently fitted to the tank, I bought another to be able to use the arduino box to measure other liquids' temperature (like my bath).

Straightforward

Straightforward. I used a guide on the arduino.cc project hub; OneWire and DallasTemperature libraries. The length of the cable is just what I needed.
