Determination of Air Quality with Unmanned Vehicles in Cement Plants

The World Health Organization considers environmental pollution to be one of its priorities for human health; their studies indicate that there is a risk at the concentrations seen in many developed countries today. To do this, the regulatory bodies in charge of environmental surveillance, protection and prevention use air quality measurement systems in the form of fixed stations located in areas of interest, generating high investment costs due to the need to replicate instrumentation systems at strategic points for data collection. Taking into account the above, this project presents an alternative solution to the problem posed by instrumenting an unmanned aerial vehicle as a displacement device and implementing a measurement system for environmental variables anchored to it. As a result, the air quality measurement system was obtained using low-cost sensors mounted on a drone. From the data obtained from the real-time system, it was possible to establish that the parameters evaluated are within the norm established for our country. It was also determined that in the area near the cement factory, the average particulate matter is 8.01 μg/m³ and carbon dioxide of 373.26 ppm, in relation to the center of Guapán with values of 6.34 μg/m³ and 158.45 ppm, respectively, therefore, the levels of contamination near the company are higher than those measured in the parish center.
