Abstract

This study presents the design and implementation of a low-cost indoor air quality monitoring and alert system capable of detecting particulate matter (〖PM〗_1.0,〖PM〗_2,5,〖PM〗_10).The system integrates real-time sensing, data acquisition, and an alert mechanism using LED indicators and a buzzer. Experimental results demonstrated strong dynamic responsiveness between particulate matter concentrations, exposure duration, and pollutant density, validating the sensor’s sensitivity and measurement stability under controlled indoor conditions. The prototype effectively detected rapid changes in air quality, issued timely alerts under unhealthy conditions, and returned toward baseline values after exposure. These findings highlight its reliability, affordability, and suitability for indoor applications, particularly in resource-limited environments.
