Abstract
El presente trabajo desarrolla un sistema de transmisión de datos a larga distancia basado en la tecnología LoRa, orientado a aplicaciones de Internet de las Cosas (IoT). LoRa es una tecnología de comunicación inalámbrica de bajo consumo energético y gran alcance, ideal para entornos donde las redes tradicionales no son viables debido a costos elevados o limitaciones de infraestructura. El proyecto abarca desde la fundamentación teórica hasta la implementación practica del sistema, incluyendo el diseño del hardware y software, asi como la validación mediante pruebas de campo en distintos entornos. Se emplean placas LoRa ESP32 y una Raspberry Pi para establecer la comunicación entre dispositivos, optimizando la eficiencia energética y la estabilidad del enlace de datos. El informe se estructura en cinco capítulos. En primer lugar, se introduce el contexto del proyecto, estableciendo los objetivos, alcances y limitaciones. Posteriormente, se presenta el marco teórico, donde se abordan los fundamentos de la tecnología LoRa y su comparación con otras soluciones de comunicación. Luego, en el capítulo de diseño e implementación, se detallan los criterios técnicos utilizados en la selección de componentes y el desarrollo del software. En el cuarto capítulo, se analizan los resultados obtenidos a partir de las pruebas de campo realizadas en diferentes escenarios. Finalmente, se presentan las conclusiones y recomendaciones, destacando los principales hallazgos y posibles mejoras para futuras implementaciones. Este trabajo busca contribuir al desarrollo de soluciones de conectividad eficiente en el ámbito de IoT, demostrando el potencial de LoRa para la transmisión de datos en aplicaciones de monitoreo remoto, optimización de recursos y automatización de procesos en diversos sectores.
This work develops a long-range data transmission system based on LoRa technology, aimed at Internet of Things (IoT) applications. LoRa is a low-power, long-range wireless communication technology, ideal for environments where traditional networks are not feasible due to high costs or infrastructure limitations. The project spans from theoretical foundations to the practical implementation of the system, including hardware and software design, as well as validation through field testing in various environments. LoRa ESP32 boards and a Raspberry Pi are used to establish communication between devices, optimizing energy efficiency and data link stability. The report is structured into five chapters. First, the project context is introduced, establishing the objectives, scope, and limitations. Next, the theoretical framework is presented, addressing the fundamentals of LoRa technology and its comparison with other communication solutions. Then, the design and implementation chapter details the technical criteria used in component selection and software development. In the fourth chapter, the results obtained from field tests conducted in different scenarios are analyzed. Finally, the conclusions and recommendations are presented, highlighting the main findings and possible improvements for future implementations. This work aims to contribute to the development of efficient connectivity solutions in the IoT field, demonstrating the potential of LoRa for data transmission in remote monitoring, resource optimization, and process automation applications across various sectors
