Environmental pollution is a factor that represents a significant healthrisk. In El Salvador, The entity in charge of monitoring air quality is theministry of Environment and Natural Resources, currently said ministry only has3 stations for monitoring air quality throughout the territory of the country.The main objective of this work was the application of internet of thingstechniques in the design and implementation of a station of remote particulatepollution monitoring in the surrounding air. As well as setting up an Internetof Things (IoT) platform for the deployment of the data collected by the remotestation. The development methodology of this research was based on the Model ofReference Architecture for IoT systems, which has as based on the developmentof system prototypes based on the correct choice of components available andsuitable for the specific environment or application. For this case, they wereused as inputs for the electronic hardware and Esp32 controller together with aWemos-Lolin development board together with a sensor of particulate mattercontamination PMS5003; by the side of software for the IoT platform wasimplemented a storage system, graphics and website based on low-cost tools Themain result obtained in this work was an IoT prototype of an electronic stationthat allows monitoring the levels of contamination by the material of particlesin the environment, whose data are accessible from any device with internetaccess through a site web, another result of this work is the configuring anIoT platform or cloud to connect wireless with the electronic station, thestorage of the data produced by it and a web visualization stage.
