Diseño de un sistema de instrumentación portátil con base en tecnología LoRaWAN para la medición de nutrientes del suelo.

Abstract

The current work presents the design and development of an innovative portable instrumentation system using LoRaWAN technology for the measurement of soil nutrients. The main objective was to create an effective and precise tool that would allow identifying and understanding the physical and chemical characteristics of soils, as well as measuring nutrient levels (NPK) reliably. In the first phase, an exhaustive investigation was carried out to understand the characteristics of the soil and its components, which was essential to adapt and calibrate the device to the different soil compositions. Subsequently, an analysis of the existing technologies used in measuring nutrient levels in the soil was carried out. The choice of LoRaWAN technology proved to be an optimal solution due to its ability to provide long-range wireless communication and low energy consumption. Based on this knowledge, the portable instrument was designed, prioritizing the accuracy and reliability of the data. measured. An autonomous system or closed-loop controlled static converters was implemented to ensure efficient operation and extend the batteries life spam. Finally, tests and validations were carried out to evaluate the effectiveness of the portable instrument in measuring soil nutrient levels. The results obtained demonstrated a high correlation between the measurements made with the device and traditional laboratory techniques, validating its reliability. and precision
