Eve Room Overview
The Eve Room is a mid-range CO2 monitor that tracks CO2, Temperature, Humidity and VOC. It uses a NDIR sensor — the technology we recommend for reliable CO2 readings — with a stated accuracy of ±75 ppm across a 0-5000 ppm measurement range. At $100, it is aimed at home use and smart home setups.
In day-to-day use, the Room offers an onboard display, so you can read levels at a glance without opening an app, plus Bluetooth and Thread connectivity for logging trends and setting alerts, plus a stationary design (USB-C powered) best suited to continuous monitoring in a fixed location.
