IoT system for CO2 level monitoring and analysis in educational environments

Abstract

From the need derived from the pandemic originated by COVID-19 regarding the development of academic activities in a face-to-face manner, respecting biosafety protocols and ensuring that the air quality in classrooms is adequate, in this article we proposed as a contribution the development of an IoT system based on free hardware and software tools and technologies for the monitoring and analysis of CO2 level in educational classrooms, which is framed in a software architecture with three architectural views: business, functional and implementation, each of which has four layers: capture, storage, analysis and visualization.
