Diseño e implementación de un sistema para mejorar la calidad del aire en un consultorio odontológico empleando tecnología IoT

Currently, the development of IoT technology evolves rapidly, allowing the incorporation of new and modern systems with lower installation costs, we find them mostly in smart cities, smart refrigerators, home automation, smart cars, among others, Therefore, the need arises to implement a system capable of monitoring, evaluating and locating contaminated areas inside a dental office to incorporate air extraction systems at strategic points in order to improve the Air Quality (IAQ) inside the dental office "San Gregorio" located in the city of Quito. The research approach is based on the analysis of statistical data, it is given from the collection and measurement of variables to obtain statistical tables or graphs using the software "IBM SPSS Stadistics" complying with its validity and reliability, the scope of the research is quantitative-experimental, since it allows in the study to examine the behavior of the phenomena from the data obtained in the environment, also the documentary research is the starting point for the development of the research due to the fact of understanding phenomena in studies related to the IAQ. As a population, the different levels of concentration of gases in ppm (percentage per million) such as: carbon dioxide (CO2), carbon monoxide (CO) and benzene (LPG) have been selected, the sample is 91 data obtained from each gas by the sensors in each area of the dental office. The instrument for data collection was programmed on the Raspberry Pi 4 (RPI4) board in conjunction with the MQ135 and MQ7 sensors. The RPI4 connects to the internet via wireless, allowing the interaction and visualization of data in real time on a web platform attractive to the user, the results obtained corroborate the alternative hypothesis for each case, a significance value of 0.00 was obtained, which when analyzed with the statistical test "T student" concludes: A monitoring system of variables related to air quality (CO, CO2, LPG) inside the San Gregorio dental office before and after the incorporation of air extraction systems with IoT technology, the IAQ concentration levels are different, observing an improvement in IAQ in polluted areas
