Sonoff AirGuard Air Quality Monitor – PM2.5 & PM10

Breathe Better. Know Your Air.

The Sonoff AirGuard Air Quality Monitor gives you a clear picture of the air around you, helping you detect fine particulate pollution before it becomes a concern.

Using a high-precision laser particle sensor, AirGuard continuously monitors PM2.5 and PM10, while also displaying temperature and humidity. The easy-to-read screen lets you see your indoor air conditions at a glance, while smart alerts can notify you when air quality changes.

🌿 Smart Air Quality Monitoring

Fine particles can come from cooking, dust, smoke, outdoor pollution and other everyday sources. AirGuard helps you understand what's happening in your environment so you can take action when needed.

Monitor:

• PM2.5 fine particulate matter

🔔 Triple Air Quality Alerts

Stay informed with three different alert methods:

This makes AirGuard particularly useful for bedrooms, living areas, offices, nurseries and other indoor spaces where air quality matters.

For example, you can use air-quality readings to help trigger a compatible air purifier, ventilation system or other smart device.
