@aaronpk What do you use for inside quality readings? I’ve seen a few reports from indoors. I have to assume the quality inside my house is no better than others, but I’d like to know for sure. (I am running the fan of my furnace which is equipped with an American Standard Accuclean integrates electrostatic filter. M)
@macgenie I had a PMS5003 sensor that I hooked up to my home automation platform. It's the sensor used in many retail AQI meters
