At $110, it is aimed at home use and smart home setups.
In day-to-day use, the DERA Indoor Air Quality Monitor 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.
