Description

Poor environmental quality represents a global challenge due to its influence on human and habitat health. Poor environmental quality is a problem of national interest in Mexico with limitations in the development of instrumentation and universal access. This problem is particularly more severe in extreme environments where the probability of technical failures increases due to climatic conditions. In this context, a low-cost measurement system was developed to measure environmental quality variables: Temperature (°C), Atmospheric Pressure (hPa), Relative Humidity (%), Particulate Matter PM1.0, PM2.5, PM10 (ug/m3), CO₂ (ppm), H₂S (ppm), and Noise (dB). The objective was to generate a database in a warm humid climate, to increase quantitative knowledge that will lead to actions to improve environmental quality in Mexican homes. To achieve this objective, an experimental method was developed with a low-cost prototype that followed a calibration and validation procedure that supports the obtained results. Measurements were performed in a social housing in Merida, Yucatan with intervals of 60 minutes for one year (July 12th, 2023, to July 12th, 2024). As a result, 7406 data points were obtained for each measured variable, which can be used by public and private actors interested in improving the user's quality of life under extreme climate conditions. It is important to note that the database with universal access to knowledge is part of the efforts to increase science-based decisions towards energy equity and security of housing in Latin America.
