Edimax AI-2002W Overview
The Edimax AI-2002W is a premium CO2 monitor that tracks CO2, Temperature, Humidity, PM2.5 and PM10. It uses a NDIR sensor — the technology we recommend for reliable CO2 readings — with a stated accuracy of ±75 ppm across a 400-5000 ppm measurement range. At $175, it is aimed at home use, smart home setups and offices.
In day-to-day use, the AI-2002W offers an onboard display, so you can read levels at a glance without opening an app, plus WiFi connectivity for logging trends and setting alerts, plus a stationary design (USB powered) best suited to continuous monitoring in a fixed location.
