Sonoff AirGuard CO2 SAWF-08P WiFi LCD Air Quality Meter

Sonoff AirGuard CO2 SAWF-08P WiFi LCD Air Quality Meter

The SAWF-08P air quality meter is a compact device for monitoring carbon dioxide concentration, temperature, and humidity in real time. Equipped with a precise NDIR sensor, a clear 3.73" LCD display, 2.4 GHz WiFi connectivity, and support for the Matter standard, it allows you to conveniently monitor the conditions in your home, office, or child's room. It offers audible and visual alarms, measurement history recording, and integration with smart home systems, facilitating a quick response to deteriorating air quality.

CO₂ Level Control

Excessive CO₂ concentration affects well-being and concentration. Air in the 400–1000 ppm range is considered safe, while values above 1000 ppm can cause fatigue, decreased productivity, and headaches. When levels exceed 1500 ppm, indoor comfort significantly decreases. Constant monitoring allows for quick decisions to ventilate or improve ventilation, resulting in better conditions for work and rest.

Precise NDIR sensor and fast response

The SAWF-08P model utilizes NDIR technology, which provides stable and accurate CO₂ measurement within a range of 400–5000 ppm. Accuracy of ±50 ppm ±5% allows you to reliably assess indoor air quality. Data refreshes approximately every 5 seconds, making changes visible almost instantly, facilitating a quick response to rising carbon dioxide levels.

3-in-1 Monitoring – CO₂, Temperature and Humidity

The device monitors not only CO₂ levels, but also temperature within a range of 0–50°C with an accuracy of ±0.5°C, and humidity from 5 to 95% RH with an accuracy of ±3%. This gives you a complete picture of room conditions in one place. It's a practical solution that helps maintain a comfortable environment in bedrooms, living rooms, offices, and even children's rooms.

Clear display and compact design

The large 3.73-inch LCD screen clearly displays current measurement values. Network status and alarm icons make it easy to monitor the device's operation. The compact dimensions and stable base allow the meter to be conveniently placed on a desk, shelf, or nightstand.

Smart Alerts and Notifications

Sonoff AirGuard CO₂ offers three types of alerts: audible alarm, light indicator, and app notifications. When a set threshold is exceeded, the device immediately notifies you of deteriorating air quality. This helps you stay informed.

Matter Integration and Voice Control

Matter support enables integration with popular smart home platforms. Pairing is achieved by scanning the Matter code, making setup easy. Once connected, you can check CO₂ levels using the voice assistant and create automations, such as activating ventilation when a specific level is exceeded.

Measurement history and data analysis

The app features a measurement history that allows you to analyze changes in CO₂ levels. The ability to view daily, weekly, or monthly data makes it easier to assess the quality of ventilation in a room and identify moments when concentrations most frequently increase. This provides practical support in maintaining a healthy microclimate on a daily basis.

Stable power and WiFi connectivity

The device is powered by a USB-C port (5V/1A), ensuring stable and uninterrupted operation. IEEE 802.11 b/g/n 2.4 GHz Wi-Fi connectivity allows for constant access to data from the app, even when you're away from home. This gives you full control over your air quality, no matter where you are.
