Air quality monitor Sonoff SAWF-07P PM2.5 Wi‑Fi with LCD display

Sonoff AirGuard SAWF-07P PM2.5 Wi‑Fi with LCD display is a compact air quality monitor designed for continuous indoor monitoring of particulate matter and basic environmental conditions. The device measures PM2.5 and PM10 concentrations, temperature and relative humidity, displays real-time values on a 3.73-inch LCD screen and transmits measurements over a 2.4 GHz Wi‑Fi connection for remote viewing and history analysis. The monitor supports Matter integration and offers adjustable audible and visual alerts when air quality thresholds are exceeded.

Advantages

The AirGuard SAWF-07P combines multiple sensors in a single unit to provide a concise overview of indoor air parameters. Its clear LCD display provides immediate readings without needing a smartphone, while Wi‑Fi connectivity and Matter compatibility enable remote monitoring and integration with smart home systems. The device records measurement history for long-term analysis and issues configurable alerts to help respond quickly to deteriorating air quality. Compact dimensions and a stable stand make it easy to place on a desk or shelf.

Suitable for

• Homes — living rooms, bedrooms and children's rooms
• Offices and workspaces where indoor air tracking is needed
• Rooms with air purifiers or ventilation systems for automation
• Monitoring during high-smog periods or seasonal heating

How to use

Place the Sonoff AirGuard SAWF-07P on a flat surface at breathing height in the room you want to monitor, avoiding direct sunlight and sources of strong drafts. Connect the device to power using the supplied USB‑C cable and complete Wi‑Fi setup via the Sonoff app or Matter pairing by scanning the code on the device. After setup, the LCD shows current PM2.5/PM10, temperature and humidity values while the app records historical data for selected intervals. Configure alert thresholds and notification preferences in the app to receive audible, visual or mobile alerts when parameters exceed chosen limits.

Usage recommendations

For representative measurements, place the monitor at least 30–50 cm away from walls and keep it away from direct airflow from heaters or air purifiers. Regularly check the recorded history in the app to identify patterns and set appropriate alert levels. If you use the device as part of an automation with a purifier or ventilation system, test the response thresholds and adjust sensor placement to ensure accurate triggering.
