SONOFF AirGuard PM2.5 and PM10 Matter Wi-Fi Air Quality Monitor SAWF-07P
The SONOFF AirGuard SAWF-07P is an intelligent air quality monitor that measures PM2.5 and PM10 particulate matter concentrations, temperature, and humidity. The device refreshes data every 2 seconds, supports the Matter standard, and connects to 2,4 GHz Wi-Fi networks.
Key features:
- Four-parameter measurement: PM2.5 concentration, PM10, temperature, and humidity.
- Fast refresh rate: air quality data updates every 2 seconds.
- Matter support: integration with compatible smart home systems.
- Wi-Fi connectivity: communication in the 2,4 GHz band.
- Measurement history: data storage for up to 12 months.
- Data export: ability to download saved results for further analysis.
- Triple alarm system: app notifications, audible alarm, and light signaling.
- Do Not Disturb mode: option to limit alarms during selected hours.
- USB-C power supply: operates with an external 5 V / 1 A power adapter.
PM2.5 and PM10 particulate matter measurement
The SONOFF AirGuard SAWF-07P monitors the concentration of PM2.5 and PM10 particulate matter that can enter rooms with outdoor air. Current measurements help determine when to turn on an air purifier, limit ventilation, or improve airflow.
Data is refreshed every 2 seconds, allowing the device to react quickly to changing conditions. In addition to particulate matter, the monitor also measures air temperature and humidity.
Integration with Matter systems
Support for the Matter standard allows the monitor to be added to compatible Smart Home systems. The device can work with Apple Home, Google Home, and Amazon Alexa, among others, depending on the features offered by the chosen ecosystem.
Sensor readings can be used in automations, for example, to trigger an air purifier, ventilation, or send notifications when a set particulate level is exceeded.

Measurement history and data analysis
The monitor allows you to store measurement history for up to 365 days. Clear charts allow you to observe changes in PM2.5 and PM10 concentrations, temperature, and humidity at different times of the day.
Saved results can be exported for further analysis. This feature makes it easy to compare data over a longer period and evaluate the effectiveness of an air purifier or ventilation system.

Notifications and alarms
The SONOFF AirGuard can inform you about deteriorating air quality via app notifications, an audible alarm, and light signaling. Alarm thresholds can be customized to your needs, and the Do Not Disturb mode allows you to limit signals during specific hours.
