Desarrollo de un sistema para determinar la calidad del agua para ser implementado en el proyecto Paramundos a partir de la implementación de sensores de bajo costo

Abstract

The document describes the design, development, and evaluation of a real-time monitoring system to measure water conductivity in the Colombian páramos, as part of the project led by the ROMA (Autonomous Mobile Robotics) research group at Universidad Distrital Francisco José de Caldas. As the main objective of the work carried out, three low-cost, precise, and adaptable sensors were implemented: turbidity, conductivity, and temperature. These sensors enable water quality monitoring and provide real-time information for decision-making in the conservation of these strategic ecosystems. The project development included the fabrication of resistive sensors, the implementation of a voltage divider to convert conductivity variations into electrical signals, and the integration of additional components such as communication modules and data storage. The system was calibrated and validated in the laboratory using reference equipment, demonstrating a linear and accurate behavior within the established operating ranges. For data transmission, the SIM800L module was used along with the Thingspeak platform, allowing real-time data to be sent to servers for monitoring and analysis. The obtained results demonstrated the effectiveness of the design and its potential application for the conservation and management of water resources. This development contributes to improving early warning tools and the capacity to respond to changes in water quality in páramo ecosystems.
