SONOFF AirGuard CO2 SAWF-08P - Indoor air quality monitor

The SONOFF AirGuard CO2 Indoor Air Quality Monitor SAWF-08P measures carbon dioxide, temperature and humidity in indoor rooms. Its NDIR infrared sensor monitors CO2 concentration, with readings refreshed every five seconds. This makes it suitable for checking changes in occupied spaces such as homes, offices and shared workspaces. A built-in LCD shows current measurements on the device. Audible and light alarms indicate when air quality needs attention, and the audible alarm can be muted.

For connected monitoring, the device uses 2.4 GHz Wi-Fi and supports Matter. Integration with Apple Home, Google Home or Amazon Alexa requires a compatible Matter ecosystem and hub. The eWeLink app provides mobile access to readings and up to 12 months of measurement history. Continuous power is supplied through USB Type-C, so the monitor needs a connected power source rather than batteries. Its PC+ABS housing is designed for desktop placement; it is not wall-mountable.
