Super bon produit, fonctionne très bien. Je les utilisent avec un NodeMcu V3.

I have probably purchased 4 or 5 of these kits - and latest kit had a bad one - ROM address failed CRC testing.... replacement was promised to be delivered in 3 days....

So I ordered these to monitor the temperature in a fish tank. The first one survived a month and died due to a crack in the sealant that allowed water in. The internals rusted out. The second one was DOA. The third one was also DOA and I took it apart to figure out what was wrong. The wires were broken inside the canister used to hold the sensor. So far that's 3/5 that did not work. The fourth one is currently in the tank, but I'm not holding out any hope of it working either.

I've determined that these work, but are extremely finicky and show about 1 degree Celsius lower than other brands of the DS18B20. They will not work on supply voltages of 3.3volts. They work on an arduino ok at 5 volts, but on Raspberry Pi, with the supply voltage of 3.3v, they will drop off the bus within about a half hour or so.

I'm new to arduino. It took me a few hours to get this working, all because of that. From what I have found, this sensor MUST work in parasitic mode, where it steals power from the sensor line during a window in the bus cycle where it's high. An on-board capacity stores enough power to keep it working during the rest of the cycle. I was unable to get it to work by supplying + to the VDD (red) wire. I had to ground the GND (black) and VDD (red) wires and while the DATA (yellow) wire runs to the digital port of your choice, it also has to be tied to +5v through a resistor. I experimented with different values and they all seemed to give me the same results. I tried 2k - 5k. My unscientific calibration test had the probe under my tongue for a couple of minutes, which gave a reading of 97.25 degrees F, when it finally settled. It took about two minutes for it to reach that reading. One degree is pretty darned good in my opinion.I got the library and the sample code from github. Can't post a link, but search for "milesburton/Arduino-Temperature-Control-Library".Note that I had to change the library to use parasitic mode, by flipping a hard-coded value in DallasTemperatur.cpp:void DallasTemperature::setOneWire(OneWire* _oneWire){_wire = _oneWire;devices = 0;parasite = true; // TODDbitResolution = 9;waitForConversion = true;checkForConversion = true;}The example that I used was "simple", from that page. Look for "tree/master/examples/Simple" project.Dimensions: the metal probe is just under 1/4" in diameter (15/64").It's exactly 1" long to the plastic base.That base is exactly 1/4" in diameter and is another 1" in length.

They work perfectly. Using for a work project where I need to monitor temperatures of hydraulic fluid. Using an arduino UNO. Be sure to attach a 4.7k resistor in parallel to the signal and positive or else it will not work.

Worked as expected, as noted they are a little slow to react, to changes in temperature, but that's to be expected as they are surrounded by a stainless steel tube. Works fine for my humidistat project,( they are not humidity sensors, but I wanted outside air, duct and environmental temperatures, to set the humidity setpoint for my project)Also its a pull up 4K7 resistor from the data to the signal line. Not a pull down, trust me it won't work that way. Didn't burn anything up, but ymmv.

These are great. Easy to set up and use with excellent water resistance in my testing so far. I've bought two sets and plan to buy more in the future. As with all small electronics on amazon, the documentation is scant but you can find plenty of references with a few web searches.
