I made something similar
https://dheera.net/projects/airmonitor/ https://dheera.net/projects/airmonitor/
I used a PMSA003I and had major problems with it -- it was always reporting 0 for AQI if the actual value was anywhere below ~100. It wasn't sensitive to low levels of pollution. Is the PMS5003 any better?
- ahaucnx 4y agoWe also used the A003 in the past and were not happy with accuracy and quality. We had quite a number of them failing early. The 5003 is a lot better in my opinion.

- 5e92cb50239222b 4y agoI've been using three PMS5003 for years. It is sensitive to minute deviations in PM concentrations. Since I live in a very polluted area, I try to stay within one room as much as possible with a purifier running on full blast. Opening an inside door for a second lets a small amount of pollution in, which the sensor notices right away (it may be only half a microgram per m³, but it always goes up reliably). I manage to keep indoor PM2.5 levels within 1% of what's happening outside, which the sensor also tracks as expected (so if outside it's 100 µg/m³, the indoor sensor shows 0-1 µg/m³, when the outside level rises to 250, my sensor starts showing 2-2.5 µg, and so on).
