RP2040PIO-DS18B20 VS counterfeit_DS18B20

I used the code from https://github.com/jondurrant/RP2040PIO-DS18B20.

I used this project to indetify it its Falimy C clone

Are you sure that it actually is a ds18b20? Most sold items are fake: https://github.com/cpetrich/counterfeit_DS18B20

Info on how to identify fakes: https://github.com/cpetrich/counterfeit_DS18B20

According to https://github.com/cpetrich/counterfeit_DS18B20 some fakes might run into crc errors. On the other hand any kind of cabling issue would probably also...

p.s., just a heads up, your DS18B20s are almost certainly fakes. I'm using some of the fakes as well, and they perform well enough for my application, but there's a real chance genuine sensors would perform better on a long network.

Looks like a counterfeit DS18B20 sensor. I think all these similar style sensors sourced from China contain counterfeit devices. See https://github.com/cpetrich/counterfeit_DS18B20

If you're using DS18B20 devices, you should probably be aware of https://github.com/cpetrich/counterfeit_DS18B20, just for general information.

I have recently purchased Sonoff DS18B20 temperature sensor. I was curious to check if it uses an original temperature sensor. For this I have tried this Arduino sketch: https://github.com/cpetrich/counterfeit_DS18B20 . To my big surprise it turned out that it has a counterfeit sensor. Could anyone test it as well and confirm or deny my findings?
