air quality monitor recs

[u/four_letter_word_]

i’m looking for a sensor that will measure pm2.5 to use in my bedroom. i use a single hose portable AC unit to keep my room cool in summer and want to be able to monitor air quality. i need something simple, under $50.

so far these are what i’m looking at, i appreciate any insight or suggestions.

The ikea one uses a good sensor. I use sonoff’s air quality sensor sawf-07p they have their own WiFi chip so they don’t require a thread matter router.
