Take control of your indoor environment with the Sonoff AirGuard CO2 Monitor . This advanced Matter-compatible device offers multi-metric environmental tracking, providing real-time data on carbon dioxide levels, ambient temperature, and humidity. Equipped with a professional NDIR (Non-Dispersive Infrared) sensor, the AirGuard delivers rapid 5 second refreshes and exceptional accuracy, ensuring you are immediately alerted to stagnant or poor-quality air.

The AirGuard goes beyond simple monitoring by offering actionable improvement advice based on your local city’s outdoor air conditions. With the ability to store and export up to one year of historical data, you can track long-term trends in your home or office. As a Matter-certified device, it bridges the gap between different ecosystems, allowing you to trigger smart scenes such as turning on a fan or ventilation system via a Sonoff switch whenever CO2 levels rise too high.
