SISTEMA AUTÓNOMO DE TELEMETRÍA A LARGA DISTANCIA LoRa – IoT DE VARIABLES AMBIENTALES (AUTONOMOUS LONG DISTANCE TELEMETRY SYSTEM LoRa – IoT OF ENVIRONMENTAL VARIABLES)
Resumen
Este trabajo presenta el desarrollo de un sistema de monitoreo remoto de variables ambientales utilizando un sistema embebido para facilitar la telemetría a larga distancia y en entornos de difícil acceso. El sistema está conformado por un nodo acoplado a un panel solar con baterías recargables para su autonomía y sin conexión a red eléctrica. El nodo se encuentra diseñado para adaptar un conjunto de sensores y de manera predeterminada está equipado con un sensor de temperatura y presión. El sistema se diseñó con el objetivo de tener una eficiencia energética alta y largas distancias de transmisión, utilizando tecnología de comunicación LoRa (Long-Range) y sistemas electrónicos apropiados. En conjunto se desarrolló un dispositivo puerta de enlace (Gateway) LoRa- Ethernet con protocolo MQTT (Message Queuing Telemetry Transport) enlazado al servidor Eclipse Mosquitto para su futuro almacenamiento y procesamiento a la nube de cómputo AWS IoT (Amazon Web Services Internet of Things). El sistema alcanzó 271.55 metros de transmisión, demostrando ser una solución innovadora para el monitoreo remoto sin depender de redes celulares comerciales, o infraestructura convencional, abriendo nuevas oportunidades para la telemetría en entornos desafiantes.

Abstract
This work presents the development of a remote monitoring system for environmental variables using an embedded system to facilitate long-distance telemetry and in difficult-to-access environments. The system is made up of a node coupled to a solar panel with rechargeable batteries for its autonomy and without connection to the electrical grid. The node is designed to accommodate a set of sensors and by default is equipped with a temperature and pressure sensor. The system was designed with the objective of having high energy efficiency and long transmission distances, using LoRa (Long-Range) communication technology and appropriate electronic systems. Together, a LoRa-Ethernet gateway device was developed with the MQTT (Message Queuing Telemetry Transport) protocol linked to the Eclipse Mosquitto server for future storage and processing in the AWS IoT (Amazon Web Services Internet of Things) computing cloud. . The system reached 271.55 meters of transmission, proving to be an innovative solution for remote monitoring without depending on commercial cellular networks, or conventional infrastructure, opening new opportunities for telemetry in challenging environments.
Keywords: Embedded system, Environmental variables, Gateway, LoRa, Node.
