Awair Omni Overview
The Awair Omni is a professional-grade CO2 monitor that tracks CO2, Temperature, Humidity, VOC, PM2.5, Light and Noise. It uses a NDIR sensor — the technology we recommend for reliable CO2 readings — with a stated accuracy of ±50 ppm across a 400-5000 ppm measurement range. At $400, it is aimed at commercial buildings, offices and professional applications.
In day-to-day use, the Omni offers an onboard display, so you can read levels at a glance without opening an app, plus WiFi and Bluetooth and Ethernet connectivity for logging trends and setting alerts, plus a stationary design (USB powered) best suited to continuous monitoring in a fixed location.
