The IQAir website collects data on the concentration of PM2.5 particles in the air, a pollutant that is often considered the most dangerous for human health.
We should recall that the data of the city of Yakutsk appeared on the IQAir platform thanks to the Sinet Spark project. As part of it, IQAir Air Visual Pro air quality sensors were purchased, which can register the concentration of suspended particles PM2.5 and transmit data from them to the Internet in real time. At the moment, three public sensors are installed in Yakutsk: in Glukhoy alley, the intersection of Dzerzhinsky - Lermontov and Khatyng-Yuryakh highway.
