Built for Smarter Indoor Air Monitoring

Indoor air can change without you noticing. Cooking, smoke, candles, dust, outdoor pollution, and everyday activities can affect particulate levels, making it difficult to know when conditions have changed simply by looking around the room.

The SONOFF AirGuard PM gives you a clearer way to monitor these changes. Its professional-grade sensing system updates PM2.5 and PM10 readings every 2 seconds, while the high-definition LCD displays your current environmental information at a glance.

Whether you want to monitor your home, check the effectiveness of an air purifier, or build a more responsive smart home air quality system, AirGuard gives you useful information when you need it.

Why Choose the SONOFF AirGuard PM2.5?

Choosing an indoor air quality monitor is about more than seeing a number on a screen. Fast readings, useful alerts, historical data, and smart home compatibility all determine how practical the device becomes in everyday use.

The SONOFF AirGuard PM combines:

Real-time PM2.5/PM10 monitoring for quickly changing particulate conditions

2-second measurement updates for responsive air quality tracking

Temperature and humidity monitoring for a broader view of your indoor environment

Matter over Wi-Fi connectivity for integration with compatible smart home platforms

Three alert methods using sound, indicator lights, and app notifications

Up to 365 days of historical data for identifying longer-term trends

Each feature is designed to make indoor air quality monitoring easier, more informative, and better suited to connected homes.

Why AirGuard PM Compared to Standard Air Quality Monitors

The Difference You Notice Immediately

See Air Quality Changes Faster

With PM2.5 and PM10 readings refreshed every 2 seconds, AirGuard helps you identify changes in particulate levels quickly. This can be useful when cooking, using candles, ventilating a room, or checking how an air purifier affects your environment.

Monitor More Than Particles

AirGuard combines PM2.5, PM10, temperature, and humidity monitoring in one compact device. Instead of relying on separate sensors, you can get several useful environmental readings from a single smart air quality monitor.

Stay Informed With Three Alerts

Receive air quality warnings through app notifications, sound alerts, and indicator lights. You can also customise the alert experience and use Do Not Disturb mode when you want quieter monitoring.

Understand Long-Term Air Quality Trends

Access and export up to 365 days of historical data, allowing you to identify recurring changes and better understand how your indoor environment behaves over time.

Build a Smarter Home

Matter compatibility allows AirGuard PM to connect with compatible ecosystems such as Apple Home, Google Home, Amazon Alexa, and SmartThings. Use air quality information as part of compatible smart home routines and automation.

How to Use the SONOFF AirGuard PM

Using the SONOFF AirGuard PM2.5 air quality monitor is straightforward:

Power the device through its USB Type-C interface.

Place it in an appropriate indoor location with its air vents unobstructed.

Connect it to the eWeLink app or a compatible Matter application.

For third-party Matter integration, use a compatible Matter hub/controller.

Monitor PM2.5/PM10, temperature, and humidity directly from the display or supported app.

Configure alerts, review historical information, and create compatible smart home automations.

The device uses 2.4GHz Wi-Fi, and its rear air vents should remain unobstructed because they are important for sensing.

Who Is It For?

The SONOFF AirGuard PM is ideal for:

Homeowners

Smart home enthusiasts

Apartment and house residents

Home office users

Families monitoring indoor conditions

Air purifier users

Nurseries and living areas

Workshops and indoor workspaces

Anyone wanting a connected PM2.5 air quality monitor

If you want more visibility into changing indoor conditions or want to add air quality monitoring to your smart home, AirGuard PM provides a practical and connected solution.

Smart Home Compatibility

AirGuard PM is designed for modern connected homes. Through Matter over Wi-Fi, it can integrate with compatible smart home platforms including Apple Home, Google Home, Amazon Alexa, and other supported ecosystems.

This gives you more flexibility when building your smart home. Instead of keeping air quality information isolated on a standalone device, you can use compatible platforms and automation routines to make your environment more responsive.

Note: Third-party Matter ecosystem integration requires a compatible Matter hub/controller. The device also supports setup through the eWeLink app.
