Implementación de sensores de bajo costo para el monitoreo de gases contaminantes y material particulado en el aire : implementación de un prototipo de módulo sensor de bajo costo para la determinación de los niveles de concentración de monóxido de carbono y material particulado pm2.5 en el aire.

Abstract

This curriculum integration work describes the development and deployment of a low-cost sensor module prototype designed to measure carbon monoxide and PM2.5 particulate matter levels in the air. This prototype is integrated into a web system that allows registered users to visualize and download air quality measurements obtained by the sensor module. The prototype utilizes the ESP32 microcontroller and connects to the Moodle learning management platform through a custom external service. Moodle serves as a central hub for managing real-time data transmitted by the sensor module. The prototype's performance is evaluated by comparing it with data provided by professional monitoring equipment located at a station within the Quito Metropolitan Atmospheric Monitoring Network. The development process follows a phased structure, spanning from initial design to configuration implementation and testing. These stages culminate in a comparative analysis that assesses the accuracy of the prototype. The purpose of this project is to establish the accuracy level of affordable sensors, aiming to promote access to air quality measurements through a low-cost technological solution.
