What exactly does a "air pollution meter" measure, and how do I get one?
- pkolaczk 2y agoIt counts pollution particles in the air by highlighting them with a ray of laser light and counting the reflections. Air cleaners usually come with a device of this kind. Or you can build one yourself by buying the sensor separately (eg. PMS7003) and attaching it to a microcontroller.
