Pluggable terminal waterproof temperature sensor can be used in many places, such as soil temperature detection, hot water tank temperature control.
Waterproof temperature sensor must also be connected to a pull-up resistor can be used, for which we designed the converter to send use.

Temperature sensor resolution: 9 to 12 adjustable resolution
Temperature range: -55°C ~ +125°C
Temperature Sensor Output Lead: Yellow(DATA) Red(VCC) and Black(GND)
Adapter Cables: DATA, VCC, BLK,
Suitable platform: for Arduino and Raspberry Pi
Programmable Resolution 1-Wire Digital Thermometer (Need to be used with pull-up resistor).

2 Pack DS18B20 Temperature Sensor Module Kit:They worked great for me.I was a little intimidated at first by the s/w interface described in the manufacturer's data sheet.But, there are free libraries (from the mfgr.) that take care of all of that so, in the end, it was very easy to integrate into the Arduino code.

One of the probe type sensors is DOA, measures 12 ohms between power wires and 40 ohms between data and either power wires, some kind of internal short. Didn't know until too late to return. TO-92 type sensors both worked well. Connection boards, female cables and case they all came in were pretty nice and would have been 5 stars if the one sensor was dead.

Could not get the Raspberry Pi to detect these.

first one worked for about 45 days, then started reading 40 degrees higher than it actaully was. plugged the second one in, and it reads normal.update. second one stopped working after a month.they're not very waterproof.

It was only after I ordered these that I realized how bad the clone problem with the DS18B20 is.These, are worse than clone products - they are counterfeits. They are physically stamped with a brand other than the one that made the chip.So pervasive is the clone issue with these chips that ready-to-use detection code is wildly available. This identified them as XSEC SE18B20 sensors.Unfortunately, unlike the genuine DS18B20's, no datasheet exists for the SE18B20.There is no specification for accuracy, consistency, or reliability of data.I have confirmed findings noted by others:Sensors do not work with Parasitic Power. Sensors draw data line low while powered parasitically.Temperature errors up to 3 °C at 0 °C, with high variability between examples.Data noisier than genuine chips.For many applications, this might be fine. For my application, I need something more precise. It is a shame these aren't just sold as "DS18B20 Compatible", then people at least know what to expect. They do take at least approximate temperature measurements using the same libraries and code as the DS18B20, albeit taking quite a bit of time - sometimes up to 500ms - to respond.Rather than declaring their status as functional, if undocumented knockoffs - Sadly, this product hopes you don't know any better. Now you do. Caveat Emptor.

I think the idea of the resistor board is great ! But the layout is wrong. For the small sensor it does not match. It should be gnd data vcc , not gnd, vcc , adta

Well manufactured and includes a sealed waterproof probe as well as the mountable board version and the resistor needed. Yes I could have saved a few buck by buying from China myself but I would have had to wait too long.,

I really like the package. The DS18B20 sensors are my favorite, since they are simple to wire and simple to use in software on the Raspberries. The housing does a good job outside in heat, rain and snow. Only the precision is not on top, since I have two sensors and both show a difference of 1.9 degrees at the exact same spot over hours. After a reboot, the difference also varies, so it is hard to measure the real temperature once and adjust the sensors with a fixed compensation during read out. Also, sometimes the sensors fails and I have to reset the w1-bus by unloading and reloading the kernel driver. I wrote a simple watchdog for this, which you can find by googleing "ds18b20 watchdog". Since then, the sensors do a nice job in reading outside temperatures on my weather terminals. The terminals had to be places close to windows, so that the cable reaches the outside. A bit of a longer cable would have make sense here.
