May I ask what you bought? I've been looking for something like this but everything I've found has been pricey.
Ecowitt everything. They whitebox for Ambientweather and others, there's a whole rundown on wxforum: https://www.wxforum.net/index.php?board=111.0
This affects temperature sensors/parts bought from un-official distributors like ebay or AliExpress, not digikey, farnel, etc. Perhaps I've been too lucky in my career and practiced EE for work, but who would you ever go to ebay instead of digikey?? Digikey certainly has a premium, but their speciality is small numbers/cut tape/etc and they have a small order size which makes them ok for hobby work, and I've used the…
I'd never expect to find these in official products from trusted brands, but off-brand crap? Oh yeah. DIY kits? Absolutely. The parts drawer at the makerspace? One hundred percent. So much stuff on eBay is free shipping, that's huge when you only need a few dollars worth of stuff. If I could convince Digi-Key to lick a 55-cent stamp when I need ten of something, instead of charging me $7 for shipping, I'd have a lot…

For example, the company FTDI snuck in code that was in a series of Windows updates that was able to detect counterfeit FTDI and brick them via software to send back all 0's.[0][1] This anti-consumer behavior on behalf of comapnies can a be a headache for end-users and programmers alike.

Anyone have an idea what these are used in? I originally thought they might be used for 3D printing, but that doesn’t seem to be the case - except, perhaps for chamber temperature.
I have several for homebrewing - monitoring mash, sparge, and fermentation temps.
Off topic but... how do you do IO on a chip that only has 3 pins? I assume you need one pin for V+ and one pin for Ground and then there's only one pin left for both I and O?
The DS18B20 is, indeed, a 1-Wire device.

I've bought hundreds of electronic parts on eBay and rarely had issues. I discovered LED strips were a thing by shopping on eBay, years ago, much before they were trendy, I was buying them at one fifth the cost American retailers were charging. Bought Arduino clones for a quarter the price of the "real" thing when I was a broke student. ATMega MCUs for a dollar a piece, free shipping. They worked perfectly fine. Coul…
99%+ of my hobbyist electronics bits n' bobs are ali express/banggood specials, and they have all worked fine, from arduino clones to sensors and ESP8266's. If I were working on something more important that dinking around for fun, sure, I might care a bit more about what's actually on the board. But as it is, the clones are more than adequate for my needs, particularly at their price point.
