Portable Device for Air Quality Monitoring and Filtration

Abstract

In this research a portable indoor air quality monitoring and filtration device is presented which could provide an effective solution for indoor environmental well-being. The proposed device intended to detect air pollutants like nitrogen dioxide (NO₂), carbon monoxide (CO), and particulate matter (PM). The device consists of typical sensors for different pollutants and filtration mechanism for improvement of the air quality facilitated with an OLED display screen. This device allows for active air filtration in the monitored indoor area. The results showed the reliability of a device in measuring pollutant levels and reducing airborne impurities over time through its filtration mechanism. The device is compact in design and powered by battery operation which makes it easy to use without needing fixed installations. Overall, this research presents a convenient solution for household use with ease of operation.
