The sensor works great! 🤩 It is small and ideal for small air quality measuring devices. It measures PM 1, PM 2.5 and PM 10 particulate matter. Good documentation and a simple UART communication protocol are also a plus. It has only one downside, that it requires 5V to power the motor (the logic works on 3.3V and this is a plus!) which requires raising the voltage when powered by 3.6V LiPo. However, this is rather a standard, because I have not been able to find a sensor that works 100% on 3.3V.
