For the average person, knowing the PM level at the current position in realtime is difficult. Most people know the level of PM from mobile apps only, which is not realtime and does not match the location, because in Bangkok there is little air quality measurement station. (In some areas of Bangkok, there is no air quality measurement ...

These sensors could be help to validate the PM sensor values. In fixed stations outside we recommend it, because we need humidity below 95% for right PM values and at the outside the meteorology varies much. We are using a AM2320 sensor that has these sensors, and it we connected to the ESP32 via i2c port. Sensirion sensor version finished:
