Design of indoor smart air sterilization system with air quality monitoring based on iot

Abstract

Airborne virus is a major concern in this pandemic era. Viruses can spread indoors even though health protocols have been implemented so the air quality in indoor environment need to be controlled. Air quality can be measured through several aspects, such as temperature, humidity, and CO2 levels. Each aspect can be analyzed for its concentration according to the predetermined threshold value of Air Quality Standard. This study offers an IoT-based smart indoor air sterilization system that can be used to monitor air quality by adding a HEPA filter, UV lamp, and carbon in air purifier. The proposed system can be monitored through the android application in real time. The test results show that the proposed system can run according to the specified parameter values given. For UV lamp is turn on, temperature produces an average temperature of 24C, CO2 level is around 314ppm, and humidity level is 45 – 65%. For further analysis, the air purifier need to be placed in different location to determine the coverage of air purifier and to examine the size of product that suit the need.
