Breathe better by knowing what’s in the air. The SONOFF AirGuard CO₂ SAWF-08P continuously monitors CO₂ levels, temperature, and humidity, helping you understand your indoor environment and know when it’s time to improve ventilation.
Accurate CO₂ Monitoring: Equipped with a professional NDIR CO₂ sensor, the AirGuard delivers high-precision readings with an accuracy of ±(50 ppm + 5%). Measurements refresh every 5 seconds, giving you up-to-date information as air conditions change.
Real-Time Temperature & Humidity: Monitor CO₂, temperature, and humidity from the same device. The clear display makes it easy to check your indoor conditions at a glance, without opening an app.
Smart Matter & Wi-Fi: Connect the AirGuard to Apple Home, Google Home, Amazon Alexa, and other Matter-compatible platforms. Create smart scenes and automations with other devices to automatically respond when CO₂ levels rise. A Matter hub is required for third-party Matter integration.
Smart Alerts & Air Quality Advice: Get notified through app notifications, sound alerts, or indicator lights when CO₂ levels need attention. The AirGuard can also combine your indoor readings with your city's outdoor air quality conditions to provide tailored suggestions for improving your environment. You can also enable Do Not Disturb Mode when you don't want alerts.
Track Your Air Over Time: Access and export up to 365 days of historical CO₂, temperature, and humidity data through the eWeLink app. Review trends to understand how ventilation, occupancy, cooking, and other activities affect your indoor air quality.
