AQ-0115V is a device that offers users behavior guides for indoor air quality management through analytic diagnosis of external and internal air. It senses five elements for comfortable indoor air care (dust, gas, CO₂, temperature, humidity) in real time, and users can intuitively see integrated air quality through four colors. AQ-0115V’s sloped design widens the area it can sense to increase performance and allows users to easily check air quality indoors. Data measured over a set time is used to more precisely analyze indoor air quality by connecting to an app, and tailored services for different types of air quality are offered.
