@ClimateJenny@biodiversity.social a smoke alarm tells me to get out of my house because it is on fire. I guess this could be interesting, but does it have any actual use?

@Fu@hostux.social For me, it (1) provides very local information on the outside air, rather than a Purple Air monitor a few miles away or a government monitoring station a dozen miles away; and (2) verifies that the in-house air filtration is doing a good job. It’s really very reassuring to bring the little box inside and watch the PM 2.5 reading drop from 200 to 5.
