Implementación de un dispositivo IoT, basado en tecnología LoRa para la geolocalización y monitoreo fisiológico de personas en lugares turísticos.

Abstract

The present work aimed to implement an IoT device, based on LoRa technology for geolocation and physiological monitoring of people in tourist places, in this case, the Reserva de Producción Faunística Chimborazo (RPFCH) was chosen. For the design and manufacture of the device, the technical and regulatory requirements necessary for its implementation were considered. Firstly, the conception and general architecture of the deployed system was established, using a star network topology, made up of a sensor node (positioning module, non-invasive physiological sensors, help button and audible alarm), a coordinator node (LoRaWAN gateway), the cloud server and the monitoring and control stage. The electronic connection diagrams of the elements were made and there were determined all the necessary software tools for programming, configuration and operation of the manufactured IoT device. In the results of the tests carried out, it was possible to evidence that communication links were established for the routes selected in the RPFCH, in line of sight, thus proving that the sensor node did not incorporate considerable errors in measurements, respecting a margin of error of 2,5 m for geographic coordinates, margin +/- 0,2 ° C for peripheral body temperature (PBT) and 2 beats per minute margin for heart rate (HR). With the above mentioned, it was concluded that the implemented system can help locate and monitor people who may suffer mishaps in tourist places. It is recommended to carry out more studies in case of future applications and also consider that this work was carried out using free software platforms, presenting the corresponding limitations.
