I love it and I want to buy one for every on of my family and friends.

Just curious though does it cover finer particles and if not just curious why? Same question I guess for a general AQI rating. The one random (probably poor quality) portable AQI monitor I have covers different levels of fine particles and that seems really useful during fire season when its bad (in Nor Cal). But of course I'm not super knowledgeable about any of this.

Anyway fantastic project, I absolutely love it.

As the sibling commenter pointed out correctly, there is no PM sensor built-in at the moment. However, we added an extension port at the back that allows connecting PM sensors like the SEN54. We also plan to support this natively in the firmware and perhaps even offer a kit sometime soon that matches the design language.

It does not have any particle detection
