A team from the Universidad Central “Marta Abreu” de Las Villas (Santa Clara, Cuba) and the Antwerp Maritime Academy will organize a workshop where Belgian and Cuban students will build together low-cost air quality monitoring systems that can measure temperature, relative humidity, CO2, NOx O3, and particulate matter. The goal of the workshop is to create from cheap sensors and other components performant measuring devices. During the workshop, the impact of pollution sources at the campus will be evaluated by performing a measuring campaign with the self-built monitoring devices. The data from the different devices located at different positions will be combined and processed. A last important issue that will be tackled in the workshop is the calibration of sensors so that the collected data can be compared with each other. Thanks to this workshop, the academic community in Cuba will receive a powerful tool to fight against pollution and climate change. This project is part of a South Initiatives, funded by VLIR-UOS.
