Awair produces several indoor air quality monitors that measure temperature, humidity, carbon dioxide, dust (PM2.5), and VOCs, accessible via mobile app: Awair, a tabletop model, Awair Baby, similar to Awair but the casing has been replaced with a copolymer, and Awair Glow, which plugs into an outlet and can power on “non-smart” devices like air purifiers when air quality drops.
