Desarrollo de una estación de monitoreo de condiciones ambientales en espacios públicos

Abstract

The growing concern about environmental quality in public spaces has driven the development of technological solutions to monitor and analyze environmental conditions in real time. This project presented the design and implementation of an environmental monitoring system that combines an ESP32 and a Raspberry Pi, along with sensors to measure key parameters such as air quality (PM2.5 and CO2), temperature, humidity, atmospheric pressure, noise, and precipitation. The integration of these devices allowed for the centralization and processing of data through an interactive dashboard in Grafana, complemented by cloud storage via InfluxDB. Additionally, the system includes educational data and feedback to raise environmental awareness among users. The system was developed using an ESP32 for data acquisition and a Raspberry Pi for storage, integrating sensors such as the AM1008W, which measures multiple parameters along with environmental sensors, ensuring redundancy. The collected data was stored in the free cloud service InfluxDB and visualized through an interactive Grafana dashboard hosted locally. The application includes a seven-inch screen and buttons, as well as allowing evaluations from users, whose results are stored in CSV format. As a result, the system provides an application for real-time monitoring of environmental parameters. Dynamic visualizations and sensor redundancy ensure reliability, while interactive tools encourage citizen participation to learn more about environmental conditions. It is concluded that the modular design and integration of accessible technologies make this system a viable solution for various contexts, highlighting its impact on environmental education in the local population.
