Development of a Low-Cost, High-Accuracy Particulate Matter (PM) Sensor for AQI Monitoring: Design and Validation of Model for Predicting AQI in Different Areas

Abstract

In Banglore, the second greatest and fastest-growing city in India, measurements of fine particulates less than or equal to 10 μm (PM10) were taken continuously using a dust-resistant sampler (APM 460 BL). We followed the usual procedures advised by the Environmental Protection Agency (EPA) for both collecting samples and following inspection for in contact with air particulates particles. The lead level fluctuated between 0.21 to 1.18 μg/m3, whereas PM10 values were recorded to range from 88.1 to 226.9 μg/m3. The yearly medians of the amounts of substances currently of significance showed that they were typically consistent with those found in the majority of other Indian metropolitan regions and were largely beneath the Indian environmental guidelines. Concurrently, the anticipated and estimated quantities of PM10 were compared in order to confirm the AERMOD framework. The information repository created by the current study on pollution levels could be utilized for additional investigations and citywide efforts to reduce pollution.
