Low-cost sensors for particulate matter measurement
Résumé
Particulate matter (PM) is a global threat to human
health, associated with respiratory, cardiovascular, and
neurological diseases, as well as premature mortality. PM
toxicity depends on several factors, size being a crucial
determinant. PM10 (< 10 μm), typically remains in the upper
tract and is less hazardous than PM2.5, which can penetrate
deeper into the lungs and PM1, which can enter the
bloodstream. Accurate measurement of fine PM is critical,
and low-cost sensors (LCS) represent a cost-effective
complement to official monitoring networks. This feasibility
study aims to compare the performance of a Wi-Fi and
two LoRaWAN air quality stations (AQ stations) using LCS
to measure PM, with the goal of determining whether the
LoRa AQ stations can deliver accurate measurements.
