Diseño y análisis de un sistema de lisimetros para macetas en la Estación de Investigación e Innovación de Ciencias de la Vida y el Desarrollo Sostenible

Abstract

The design of technological tools for monitoring and analyzing agronomic variables has become increasingly relevant due to the need to enhance water management efficiency and agricultural productivity. Weighing lysimeters stand out as devices capable of measuring soil water dynamics, providing precise data on weight changes associated with water consumption in pots. However, the implementation of accessible systems tailored to specific conditions remains a significant technical challenge. This study presents the design and analysis of a weighing lysimeter system, focused on integrating advanced technologies such as load cells and moisture sensors. This approach establishes a system that records weight variations in real time and directly relates them to the water balance in pots. Structural analysis of the components was conducted using SolidWorks software, ensuring the design’s integrity and functionality before its physical construction. The developed prototype incorporates an electronic system for data acquisition and processing through a microcontroller, enabling efficient control of the measurements performed. Experimental tests aim to validate the system’s performance and its ability to accurately measure soil conditions in pots. This project represents a technical contribution to the field of agronomic instrumentation, aiming to optimize monitoring processes in research stations and controlled crop studies.
