Sistema de monitoreo inalámbrico de una piscícola con tecnología LoRa para la producción de truchas en Valle Hermoso - Pelileo

Abstract

The present research work details the design and implementation of a prototype for a wireless monitoring system of a fish farm with LoRa technology for the production of trout in the Pelileo canton, which was installed in the ponds of the fish farm "San Vicente" in “Valle Hermoso”. The wireless monitoring system of a fish farm consists of three stages: end nodes, gateway and server. The final nodes are made up of analog and digital sensors installed in the trout value ponds for each stage of development, such as fingerlings, juveniles and fattening, which allow temperature, pH, turbidity and water level to be obtained. Information. Collected is sent to the Gateway using LoRa communication, likewise the information is sent to a website located on the local server, in this stage the light communication protocol MQTT was transmitted, the information published in the mosquitto broker is shown in a web interface developed in Node-Red through its visual programming in dashboards, the interface allows choosing the type of monitored pond and presenting the acquired values of the magnitudes at that moment, in addition, the data is stored in a database with the objective of Periodically record the quality of the water and make decisions in order to improve production. The system is made up of alerts that are sent by mail and by Telegram, they are to generate warnings to the owner when the measurements are outside the normal range, in order to reduce product losses due to inadequate defects. The prototype of the wireless fish monitoring system with LoRa technology is designed to be applied in places dedicated to fish farming, in addition, due to the great range in data transmission that borders open areas up to 20 km, it facilitates the owner to save time and resources. Due to the advantage of monitoring the water parameters without the need to travel to the study site, the prototype was subjected to several performance tests over a period of two months at the “San Vicente” fish farm in Pelileo.
