Sonoff AirGuard CO2 SAWF-08P air quality monitor with Matter over Wi-Fi

That heavy-headed feeling after hours in a closed room usually points to CO2 build-up, and the AirGuard CO2 tracks it with an NDIR sensor refreshing every 5 seconds.

When the enemy is dust — traffic outside, a wood stove, fresh renovation — this AirGuard is the one: SAWF-07P reads PM2.5/PM10 every 2 seconds and alerts by light, sound and push.
