Sistema de adquisición de datos meteorológicos para la medición de la calidad de aire a través de Arduino.

Abstract

The meteorological station project arose from an exhaustive search for documents on air pollution and monitoring in urban centers given the large growth of automobiles and industrial parks in which they become sources of air pollution, with the purpose of making a system for collecting meteorological data for air quality control through an open source platform called Arduino, through the implementation of the use of open source hardware and software in the creation of devices that help monitor and inspect air quality. The weather station is low cost and helpful because it takes atmospheric and airborne gas variables such as temperature, humidity, air pressure, alcohol, CH4, NH4, CO2, VOC, latitude, longitude and date. To carry out the data collection of polluting gases, it was necessary to use gas sensors, which were not calibrated, so a calibration of the components of the MQ gas sensors was made, for this a linear mathematical model was created through the manufacturers data sheet, creating libraries for the MQ series, which are competent and ideal for data collection regarding air quality, which leads to decision making, for the improvement of quality of life in urban centers.
