Development of a сost-еffective air quality monitoring devic

Abstract

Air pollution has a significant negative impact on human health and the environment. Existing air quality monitoring systems have limitations due to high equipment costs and insufficient spatial resolution. The aim of the work is to develop and study a low-cost air quality monitoring device based on the PMS7003 particulate matter sensor and ESP32 microcontroller.
The structural and schematic diagrams of the device have been developed, and a working prototype has been manufactured. Calibration and testing of the device in laboratory and real conditions have been conducted. A comparative analysis of the device characteristics with existing analogues in terms of accuracy and cost has been performed. It has been established that the developed device has sufficient measurement accuracy at a significantly lower cost compared to commercial analyzers.
The prospects for using the device to create extensive air quality monitoring networks in urban environments have been evaluated. It has been shown that due to its low cost and compact size, the developed device can become the basis for deploying scalable and flexible monitoring systems with high spatial resolution, which will optimize environmental protection measures and increase public environmental awareness.
