Diseño y simulación de un sistema de adquisición de datos y tracking del proceso productivo de café: Diseño y simulación del sistema de adquisición de datos en IoT con LoRaWAN para el proceso de secado de café.

Abstract

This Degree Work presents the design and simulation of a data acquisition system with LoRaWAN communication technology, designing a final node that connects to The Things Network to later be linked to IoT applications for data visualization and analysis Chapter 1 defines the basic concepts related to LoRa technology and the LoRaWAN communication protocol, determines the influential variables in the coffee drying process, details the characteristics of the Arduino card and various sensors, and analyzes the importance of IoT in modern applications linked to LoRa. Chapter 2 details and justifies the selection of the elements for the design of the final node, the programming for the acquisition of sensor data and the programming for the communication of the final node with the network through LoRaWAN is carried out, the procedure is detailed. to follow to link the network to IoT applications and the control algorithm for humidity in the coffee drying process is carried out. Chapter 3 shows the simulations of sending data from the end node to the network and from the network to IoT applications, graphical interfaces, histograms, maps, etc. offered by these applications for data visualization and analysis, and the response of the designed controller to reference changes. The conclusions and recommendations of the development of the work are indicated based on the result of the simulations.
