PurpleAir Flex Air Quality Monitor / PA-II-FLEX

The PurpleAir Flex is the latest air quality monitor from PurpleAir, measuring real-time PM2.5 concentrations for residential, commercial, or industrial use. Containing a full-color LED, the resulting glow indicates real-time air quality at a glance and can be installed indoors or outdoors.

PurpleAir is so cool they tell you exactly what sensors they use on their website. Anyways here is my $50 yogurt container that tells me when should close my windows because of wildfire smoke. : r/arduino

Air Quality Monitors from USD 169 to 6k use the same low-cost PM Modules
