AZDelivery 5 x DS18B20 1M Cable Temperature Digital Thermal Probe Sensor compatible with Arduino and Raspberry Pi including E-Book!

Apparently there are a lot of DS18B20 "clones" getting sold which aren't fully compliant with the spec, but these appear to be the real ones or at least very good clones (it's difficult to know because of the waterproof packaging.)I only needed one or two for a software demo, but now I've got some spare ones.Really easy to integrate on a Raspberry Pi with 1-Wire support configured - to the extent you could probably make something useful with a shell script without the need for a library in a high level language.

I use these Temperature Digital Probes on my ESP8266 projects. I have stuck 2 of them to the hot water tank, one about centre and one near the top, The reading is displayed on a really old ipad in the kitchen. It is useful to see how hot the water is and know that the shower will not run out. I also had a third in the loft cold water tank to see its temperature. When the probe is totally immersed in water it only worked for about a year so I guess it was not totally water proof. I now have it stuck to the outside

I bought two, they work fine but even one next to each other, they don't measure the same temperature! 0.5C difference..

There products always work well, and usually better quality than similar items at a similar price, plus they have useful instructional information.

Great value - only needed two sensors for my project, so I've three spares that I can deploy elsewhere. Very easy to prototype on a breadboard with a PI Zero. I had data flowing in minutes. Identified each probe connected by placing them in boiling water and seeing the temperature reading change accordingly. Tested by placing in ice water. They are reading consistently but I can't speak to their accuracy - for my project I'm more interested in consistent readings for comparison and rate of change to identify conditions.Would certainly buy again for future projects.

AZDelivery is my go to for small electronics, no exception with these temp sensors. Used on a hot water tank with an ESP to automate heating controls. Very accurate too.

I wanted a fairly robust temperature sensor for use with an Arduino. Now that I have sorted out my code and carried out some prototyping, I am delighted to advise that these units are perfect for my application. The temperature readings are consistent and accurate enough for my purposes.
