Smart air purifier suitable for small public spaces

摘要

The article presents the concept and implemented, functional physical model of a mobile air purifier for small public spaces or apartments. The purifier is a compact, controlled by microcontroller of the Arduino UNO series. The model is equipped with a set of sensors allowing to determine the content of PM 2.5 contaminants. After exceeding the adopted threshold in the software, the system automatically starts the process of air filtering. The following factors are measured: solid contamination content, humidity and air temperature as well as pressure drop on built-in filters. The purifier absorbs solid pollutants and reduces VOC pollutants. The system has been equipped with a screen informing the user about air parameters and the state of the filter contamination.
