Fun Friday night project: set up a PM2.5 sensor inside and hooked it up to my home automation hub, and now have a display on the wall showing the terrible terrible inside and outside AQI

Is the inside AQI so much lower just from keeping the doors / windows closed, or do you have active filtration running?

We're in an apartment so there's some building wide filtering for the hallway. Keeping all outside doors/windows closed, and running an AC. No special filters tho.

Which sensor and hub do you have? I've been wanting a wearable sensor that also measures tvoc, carbon monoxide, and carbon dioxide

It's the PMS5003 sensor that's in a whole bunch of devices. It'd be a real challenge to make it wearable but that sounds like fun!
