I've had a Plantower PMS5003 air quality sensor running outside to measure the PM values for a few years now, I already had to replace the sensor a couple of years ago and now the current one is dying too. I figured there had to be alternatives to that specific sensor, and it turns out the company Sensiron that makes the so-far extremely excellent SHT30 I'm using for temperature and humidity outside also make an air quality sensor. I ordered one and it arrived today, so that's yet another project to add to my list. 😅
I also bought another indoor air quality sensor that measures TVOC and eCO2 to put into the back room to see how dreadful the air quality gets when I'm airbrushing in there.
