Airthings Wave Plus is the first battery operated smart indoor air quality monitor with radon detection, including sensors for TVOCS (airborne chemicals), humidity, temperature, CO2, and pressure. You can access all of your data through the free Airthings app on your smart device, or via the Airthings online dashboard. The Wave Plus is designed to be used by anyone in all populated spaces or at home. It?s easy to use as a stand-alone unit, or as one of many in an Airthings Ecosystem. Even without app access, one can simply wave to receive a visual indicator of the indoor air quality levels.
