Hotspot identification with portable low-cost particulate matter sensor
Abstract
Air quality measurements were conducted at rural and urban environment with a low-cost particulate matter (PM) sensor and GPS receiver based portable device, which was developed to determine the atmospheric PM concentration and distribution. Using the PM sensors and GPS receiver data, hotspots can be identified, the air quality characteristics of crawled areas and routes can be determined. Suggestions was made to improve the accuracy of the measurement.
