Sonoff AirGuard Quality Monitor PM

Sonoff Air Quality Monitor PM – Smart Indoor Air Quality Tracking

Real-Time Indoor Air Quality Monitoring

The SONOFF AirGuard PM2.5/PM10 is a smart indoor air-quality monitor designed to keep you informed about particulate levels in your environment. It monitors PM2.5 or PM10 concentrations together with temperature and humidity, providing a convenient overview of your indoor conditions on its LCD display.

Monitor PM2.5 and PM10 Levels

The AirGuard PM2.5/PM10 can switch between PM2.5 and PM10 detection modes, allowing you to focus on the particulate measurement relevant to your monitoring needs. Air-quality readings are updated every 2 seconds for responsive monitoring when conditions change.

Temperature & Humidity Monitoring

In addition to particulate matter, the AirGuard displays the current temperature and humidity, making it a useful multi-purpose environmental monitor for bedrooms, living areas, offices, workspaces and other indoor environments.

Matter Over WiFi Smart Home Integration

The SAWF-07P supports Matter over 2.4GHz WiFi and can be integrated with compatible smart-home ecosystems including Apple Home, Google Home and Amazon Alexa. Integration with third-party Matter ecosystems requires a compatible Matter hub.

Smart Air Quality Advice

The AirGuard can analyse indoor PM2.5/PM10 readings together with the local outdoor Air Quality Index to provide suggestions aimed at helping you improve your indoor air conditions.

Three Customisable Alert Methods

Stay informed when configured air-quality conditions require attention. The AirGuard supports app notifications, audible alerts and indicator-light warnings. A Do Not Disturb mode can also be used to reduce interruptions during selected periods.

Up to One Year of Historical Data

Use the eWeLink app to review historical environmental information and export recorded data. SONOFF specifies storage of up to 365 days of historical records, helping you identify longer-term patterns in indoor air quality.

Large LCD Display

The built-in high-definition LCD provides an easy-to-read view of the monitored values, while the integrated multicolour LED indicator provides an additional visual indication of air-quality conditions.

Desktop-Friendly Design

The AirGuard PM2.5/PM10 is designed for desktop placement and includes a built-in stand. SONOFF advises against direct wall mounting because the rear ventilation openings are required for air detection and mounting against a wall may affect measurement accuracy.

Smart Home Air Quality Monitoring

Connect the AirGuard to your existing smart-home environment to make air-quality information more accessible. With Matter support, compatible ecosystems can use the monitor as part of broader smart-home automations.
