Sistema prototipo para el monitoreo inalámbrico de gases contaminantes del aire desarrollado bajo plataformas de hardware y software libre

Abstract

In this project, we designed and implemented a prototype system for wireless monitoring of air polluting gases such as: CO, O3 and NO2 gases using free hardware and software platforms. We initially did a general description about Quito's Atmospheric Monitoring Network (REMMAQ) concerning CO, O3 and NO2 gases, also a review of national and local regulations for monitoring and environmental control. We consequently did a brief review of related studies. We not only presented the technology used in the prototype system but also analyzed its characteristics and technical performance. Additionally, Single Board Microcontroller (SBM) Arduino UNO and Single Board Microcomputer (SBC) Raspberry Pi features are described. Subsequently, we proceed to design and implement the transmitter and receiver subsystem that compliance with the stages of acquisition, processing, sending and display of information about pollution. In addition, we developed a web interface connected to the Internet, which allows the user to visualize the information acquired through a pollution map. Finally, we tested the prototype system, and we presented the results and indicated the reference project costs.
