Stop breathing invisible danger. You can't see it. You can't smell it. But bad air is making you tired, foggy, and unwell every single day. This CO2 monitor shows you exactly what's floating around your home – and helps you fix it before it hurts your family.

Why you need this monitor

15 things your air hides from you – CO₂, carbon monoxide, formaldehyde, TVOC, PM2.5, PM10, temperature, humidity, and more. One screen tells you everything. No other device gives you this complete picture.

Stop guessing if your air is safe. The bright 2.8‑inch colour screen turns green when your air is good, orange when it's getting risky, and red when you need to open windows NOW. Your eyes tell you everything in half a second.

Know what's poisoning your air – formaldehyde from new furniture. CO from that gas stove. PM2.5 from cooking and candles. TVOC from paint and cleaners. This detector catches them all.

See your air from anywhere. Connect to the Tuya Smart app. Check CO₂ levels from work. Get alerts when pollution spikes. See weekly and monthly trends. Know exactly when your home breathes clean.

Set your own danger zones. Pregnant? Asthmatic? Sensitive to chemicals? Adjust the alarms to YOUR body, not factory defaults. Get notified before levels hurt you.

A: Infrared sensors for particles, semiconductor sensors for gases. Self‑calibrating technology keeps readings lab‑grade. No cheap toy sensors here.
