    5.0 out of 5 stars A great sensor for a RPi 3
    Reviewed in the United States on September 6, 2016

    Following a few tutorials I found online, I was able to get this working pretty quickly with my Raspberry PI 3. It is accurate and I compared it with another digital thermometer to confirm the values and they lined up perfect. I especially like that it comes with a sturdy cable and head for the sensor since that will make it easy to put the sensor far from the PI. Most impressive is that to get it to work with Python (or probably any language) requires no drives. You just need to read from the device (/sys/bus/...) and you have your data. That is cool and easy.

    If you are looking for a simple to configure temperature sensor, this is an inexpensive and accurate solution.

    I use this sensor with either my Raspberry pi or Arduino (depending on which one I'm using that day) to read the temperature of the water bath in my sous vide contraption. I've checked the temperatures versus several other thermometers and it's pretty spot on. Unfortunately it does not include a data sheet, although the DS18B20 sensor is well documented across the internet (look up the 1-Wire protocol if interested). There are also several libraries and such written out there for interfacing with this sensor. After about 10 trials of 2+ hours in a hot water bath, I have yet to notice any corrosion of the metallic tip.

    I had my eye on a DHT22 for some time due to great reviews, but it was sold out so I had to make another choice. I researched how to use this sensor with the OneWire library and initially thought it sounded more difficult, but it ended up being fairly simple and I had it working in a matter of minutes. Although I would have been more impressed if a 4.7Kohm pull-up resistor was included with the purchase, it was not enough to affect my rating. This sensor provides great accuracy and updates quickly, so it serves its purpose and I'm happy with the purchase.

    3.0 out of 5 stars How much work is needed?
    Reviewed in the United States on June 27, 2016
    Verified Purchase
    I ordered this for a hydroponics system I'm working on and haven't been able to use it yet but from the looks of it, I sort of like/hate it. From previous reviews, the leads are of a really thin gauge and stranded which made any connections very difficult. To resolve this, I had some F/F jumpers and I twisted the strands of the sensor into a more solid piece so I can insert it into the jumper. From there, I used some heat shrink tubing over it and hot glue to keep it tight and have a good connection. The other issue is that this sensor requires a resistor to work with the one wire library. I did have to use my breadboard to make it happen but later, I used another jumper set M/M and connected that to the F/F jumper. I then had to tape and shrink and glue that connection. I then cut the Data jumper wire and placed the 4.7k resistor. Hot glue and tape later, was able to successfully utilize the sensor. It did also add some more length to it but that wasn't an issue. The work I had to do on it was needed but definitely not appreciated. I wouldn't recommend this to anyone who needed one of these sensors and doesn't like work but I would use another one for myself.

    1.0 out of 5 stars No data sheet, no link, no nothing
    Reviewed in the United States on June 24, 2013

    While I am perfectly capable of downloading a DS18B20 data sheet, I would expect at least to get something that tells me what wire hooks up to what. I presume it is red = +5, black = GND, Whte = data? But, you know what they say about the word assume. Decades in EE have taught me to read the data sheet.

    A brief appnot on use? Too much to expect?

    search adafruit.com--same item, same price plus some info on how to use it.

    Do yourself a favor and look for a version of this probe that has soldered ends. I tried to strop the casing off and solder the ends and ended up throwing this away. Other versions are a bit heavier gauge and have soldered ends.

    The device itself is quite a bit more expensive than the part inside, but I cannot complain - the housing appears to be stainless steel, the cord is long and flexible. Would have taken me more time and money to insulate the sensor this way myself. We hooked a pair of those to Arduino to control the TEC element. Works great.

    I purchased a used three person dry sauna and after hours of checking and testing it would not turn the heating panels on without knowing what the present temperature is. Manufacture had this identical sensor for six times this price, not including shipping. I checked the spec's and they are identical. It took less than two weeks to arrive and is wired to the black and yellow leads. The sauna is now functioning correctly. This is not a sturdy sensor, probably has a glass core, so do not rap it on anything and expect it to work. I gave it a firm mount and it will not be touched. Cross my fingers and hope it lasts.
