Sonoff Air Quality Monitor PM2.5 - Matter Air Quality Sensor

💨 Sonoff SAWF-07P - Matter PM2.5 Air Quality Sensor

Sonoff AirGuard PM2.5 and PM10 (SAWF-07P) is an air quality monitor compatible with Matter over Wi-Fi technology that measures and displays concentrations of PM2.5 and PM10 particles, while tracking temperature and humidity. Real-time displays and in-app charts provide a comprehensive overview for long-term monitoring.

Engineered with professional precision, the device refreshes air quality data every two seconds, ensuring you stay informed of environmental changes as soon as they happen.

Why Monitor PM2.5 / PM10?

PM2.5 / PM10 refer to fine, inhalable particles emitted from sources such as vehicles, factories, and fires. Long-term exposure can increase the risk of health issues, including asthma, heart disease, and lung cancer – which is why it pays to have a PM2.5 monitor directly in the room where you spend the most time.

📝 Particulate Matter (PM) consists of tiny solid or liquid particles suspended in the air. These particles are categorized by size: PM10, PM2.5, and PM1 – representing particles with diameters smaller than 10, 2.5, and 1 micrometer respectively.

3 Customizable Alert Methods

Receive instant alerts through 3 methods: app notifications, audible, and visual alarms, ensuring you never miss critical air quality changes and stay protected against adverse indoor conditions. Customize your preferences and set "Do Not Disturb" mode so you won't be interrupted when you need peace and quiet.

Matter-Compatible Integration

Supports the Matter protocol, allowing seamless connection to Apple Home, Amazon Alexa, Google Home, and other major platforms. Easily build automations with third-party devices for a more connected smart home.

*📝 Integrating AirGuard PM2.5 with a third-party Matter ecosystem requires a Matter hub

Works Perfectly with Apple Ecosystem – Full Support for Siri, iPhone, iPad, and Apple Watch.

Hands-Free Control

Hands-free air quality checks with instant response, no app required.

📝 Requires smart speakers with supported third-party voice platforms.

1-Year Historical Data Storage and Export

Stores air quality records for the past year and supports data export, providing a solid foundation for long-term analysis and insights into indoor air quality. Visualize trends on intuitive charts to pinpoint the root causes of air quality changes.

Tailored Air Quality Recommendations

Analyzes indoor PM2.5 / PM10 levels alongside your local Air Quality Index (AQI) to provide targeted and actionable suggestions for improving your air quality.

Larger Surface Area, More Accurate Data

A larger surface area for particle contact enhances measurement precision and data reliability.
