Our take
The cheaper way to watch CO₂ remotely. Like the Aranet4 it uses an NDIR sensor, the accurate kind, but it sends readings over Wi-Fi to the Qingping+ app, which can alert you when a room passes a level you set.
It doesn't measure particles; pair it with a purifier's sensor or a PM2.5 monitor on smoggy days.
It doesn't measure particles (PM2.5).
Good for
- Watching a bedroom's or classroom's CO₂ from your phone
- A low-cost NDIR CO₂ reading
Skip it if
- You want PM2.5 too: the Qingping Air Monitor 2 reads both

How we judge. We haven't tested the CO₂ & Temp & RH Monitor in a lab of our own. The figures come from independent ratings (AHAM, Energy Star, NIOSH, the ASPCA) or the maker, and the verdict is ours, from those figures. No brand pays to be listed. Last checked Nov 7, 2026.
