SMART AIR FILTER SYSTEM

Abstract

In this article, the author focuses on building a smart dust filter system applied to life to clean the air, minimize the harmful effects of air pollution, especially pollution caused by small dust. Results through experimental cases and surveys showed that the system automatically updated the value of PM (Particulate Matter) 2.5 (size of diameter less than or equal to 2.5 micrometres) and PM10 (diameter size less than or equal to 10 micrometres) dust concentrations. Based on that, if the small dust concentration exceeds the allowable threshold, the air purification function is activated: Increasing the the exhaust fan speed to increase air flow through the system; The mist generator is turned on to moisten the air and increase the dust size, making the air filtration through the activated carbon filter and the heppa filter maximally effective. In addition, the author builds an application on the Android operating system with the name ICTUAir which can display information about the small dust index in the air at the locations in the Google maps. The GIS map website has the ability to update information on the level of air pollution based on data automatically uploaded from the system location.
