Field performance of a low-cost sensor in the monitoring of particulate matter in Santiago, Chile.

ABSTRACT: Integration of low-cost air quality sensors with the internet of things (IoT) has become a feasible approach towards the development of smart cities. Several studies have assessed the performance of low-cost air quality sensors by comparing their measurements with reference instruments. We examined the performance of a low-cost IoT particulate matter (PM₁₀ and PM_2.5) sensor in the urban environment of Santiago, Chile. The prototype was assembled from a PM₁₀-PM_2.5 sensor (SDS011), a temperature and relative humidity sensor (BME280) and an IoT board (ESP8266/Node MCU). Field tests were conducted at three regulatory monitoring stations during the 2018 austral winter and spring seasons. The sensors at each site were operated in parallel with continuo
