Construcción de un Sistema Monitoreo de Variables Agro-técnicas Basado en Sensores de Bajo Costo y Tecnología IoT, que Permita la Transmisión Inalámbrica y Adquisición de Datos en un Servidor, con el Propósito de Integrarse a un Sistema de Riego Aplicando Principios Agricultura 4.0

Abstract

This research project was initiated with the support of the FODEIN call from Santo Tomas University, which promotes the development of Tomasina research and innovation. Building upon this opportunity, the work was carried out, taking into account the issues surrounding the limited technological advancement in the Colombian agricultural sector and the wastage of water resources. Consequently, the goal was to implement a monitoring system for agro-technical variables, with a focus on Theobroma cacao crops, utilizing low-cost sensors and IoT technology, with the aim of integrating them into an irrigation system. For this purpose, a prototype of the 1.0 device designed by the authors was considered. It was redesigned to optimize processes and add sensors that would provide useful information for the system. To resolve and validate the project, field tests were conducted in Piedecuesta, Santander, specifically in agricultural crops owned by the institution, as well as in open fields and a laboratory. These tests yielded positive results, demonstrating the considerable progress that the implementation of these systems can bring to a country where agriculture is a significant pillar of the economy and sustainability, while also creating opportunities for technological and research growth.
