Resumen

This paper proposes implementing an automated hydroponic system that uses sensors for nutrient monitoring and control by measuring the electrical conductivity of the substrate. The system includes the control of a water oxygenation pump and pH and conductivity sensors connected to an ESP32 microcontroller. In addition, the monitoring system incorporates LoraWAN communication modules, which allow transmitting sensor data over distances exceeding 8 kilometres, which is ideal for applications in large agricultural environments. This device sends the collected data to a server in the cloud, where it is processed in an analysis layer. As a result, optimal control of seedling growth is achieved, in addition to obtaining a data set of different variables and finally identifying key variables that influence plant development. .
