Made a small project this week-end, using a RPI (mysql Grafana and a 7inch screen) and two custom sensor based on ESP32 I made a small meteo station to replace the one dead few weeks ago :) I still need to make pcb to cleanup the mess and make some lasercut box :) By the way I have huge doubt about reliability of the PMS5003 sensor.
@dug I'm not sure how the algorithm for the count extrapolate some value. All in all I can't say measurement are correct but they are coherent, when cooking inside sensor increase, when there are stuff going on outside, outside sensor increase followed by the inside one. I still find their measurement noisy and sometime there are weird peak (but I'm wondering if it could be related to the change in light with the sun).
