The compact Sonoff AirGuard CO2 air quality monitor with a precise NDIR sensor measures CO₂, temperature, and humidity in real time. It features a 3.73" LCD display, 2.4 GHz Wi‑Fi, Matter support, audible and visual alarms, and measurement history, giving you insight into conditions at home, in the office, or in the kids’ room.
Maintain a healthy indoor environment with a device that monitors CO₂ concentration, temperature, and humidity in one place. The NDIR sensor delivers stable, accurate measurements across 400–5000 ppm with ±50 ppm ±5% accuracy, updating roughly every 5 seconds. The large 3.73" LCD clearly shows readings and status icons, while the compact design suits a desk, shelf, or nightstand.
With 2.4 GHz Wi‑Fi and Matter support, you can easily integrate the device into your smart home, create automations (e.g., start ventilation when a threshold is exceeded), and receive in‑app notifications. When air quality worsens, audible and visual alarms alert you, so you know when to air out the room. USB‑C 5 V/1 A power ensures stable operation without battery replacements.
Key benefits:
- 3‑in‑1 monitoring: CO₂, temperature (0–50 °C, ±0.5 °C), and humidity (5–95% RH, ±3%).
- Accurate NDIR sensor with ~5 s response.
- Smart integration via Matter and 2.4 GHz Wi‑Fi.
- Alarms and history for better oversight and timely action.
- Easy placement and a readable 3.73" LCD display.
