SONOFF AirGuard PM2.5 & PM10 (SAWF-07P) is a Matter over Wi-Fi capable air quality monitor that measures and displays the concentration of airborne dust PM2.5 and PM10 in real time. The device warns of limit values ​​being exceeded with visual and application alarms, thus helping with conscious ventilation and improving indoor air quality.

Thanks to Matter support, AirGuard PM can be easily connected to Apple Home, Google Home, Amazon Alexa and SmartThings systems. The measured values ​​can also be used in automations – for example, to start an air exchanger, extractor or air purifier in the event of a high particle level.

The device has a clean design, is portable, powered by USB-C, and supports long-term tracking with a continuous display and detailed app charts.

Airborne dust (particulate pollution) consists of small, solid or liquid particles that enter the air directly or are formed from reactions of other pollutants in the atmosphere. The particles can be divided into three main categories according to their size: PM10, PM2.5 and PM1, i.e. particles smaller than 10, 2.5 and 1 micrometer in diameter respectively.
