Compatible chips, clones and fakes

The market is full of bad DS18B20 clones. Among the counterfeit sensors and poor-quality replacements sold as originals, you can easily find those that not only do not meet the specifications, but also do not work in parasitic mode. For this reason, the sensors we sell are tested with a script written by Chris Petrich. The script allows you to check and classify the sensors accurately.

Low price is very important factor. Our customers often look for the cheapest DS18B20 sensors. To be fair to customers, we decided that introducing the QT18B20 to the offer would be a good compromise between quality and price.
