Sonoff SAWF-08P AirGuard WiFi CO2 Air Quality Monitor with 3.73" LCD - NDIR Sensor, Matter, CO2/Temperature/Humidity
Breathe easier and stay focused with the Sonoff AirGuard CO2 SAWF-08P - a compact air quality monitor that tracks CO2, temperature, and humidity in real time. Using a precise NDIR sensor, it measures CO2 from 400 to 5000ppm and refreshes data about every 5 seconds, so you can spot rising levels quickly and decide when to ventilate. The large 3.73" LCD clearly shows current readings, while audible and visual alerts help you react immediately when air quality drops.
With 2.4GHz WiFi and Matter support, AirGuard fits seamlessly into modern smart home setups. Check readings in the app even when you are away, receive notifications when thresholds are exceeded, and build automations - for example turning on ventilation when CO2 rises. Measurement history (daily, weekly, monthly) helps you understand patterns and improve the indoor climate in your home, office, or child's room.

Why This Product Is Perfect to Buy
AirGuard makes indoor air quality easy to understand and easy to improve. You get fast, accurate CO2 readings from an NDIR sensor, plus temperature and humidity in one device, so you can make smarter decisions about ventilation and comfort. Alerts and app notifications help you react immediately, while history tracking helps you identify when and why CO2 spikes happen. Matter support adds extra value by letting you connect it into broader smart home routines without locking you into a single platform.
Interesting Facts About CO2 Monitors and NDIR Sensors
NDIR (non-dispersive infrared) sensors are widely used for CO2 monitoring because they measure CO2 by detecting how infrared light is absorbed, which can deliver stable readings over time. Indoor CO2 levels often rise quickly in closed rooms with multiple people, and monitoring helps you ventilate at the right moment - improving comfort and supporting better focus, especially in offices, study spaces, and bedrooms.
