I've deployed the Awair Element which does all of that but is on the pricier end. If I had to start over again I'd probably try the AIR-1 from Apollo Automation.

I use the Air-1 from Apollo for my smoke detection and it works very well!!

They do offer a gas sensor that can be added to it.

Those are the sensors it offers without any add-ons:

AIR-1 Air Quality Sensor For Home Assistant | Apollo Automation

The Apollo AIR-1 is the most compact, feature-rich, affordable, and expandable air sensor for Home Assistant. Updated for better particulate matter isolation!

#

This is a custom sensor, it does not come by default btw but it does show on the device entities.

But it's useful as it detects rising PM1 particulates

I can answer any questions or do tests if you need 🙂
