Diseño de un prototipo de invernadero con control PID de radiación ultravioleta (UV) utilizando un ESP32

Abstract

The development of the automatic winding control will be divided into several stages in which are included the theoretical research, the PLC programming, the development of the HMI interface for the visualization of each stage of the process and the configuration of the servomotor parameters for the precise winding of the coil. In this thesis, an automated greenhouse prototype is designed and implemented to optimize the control of ultraviolet (UV) radiation, a key variable for crop development. The lack of adequate regulation of UV radiation, as well as parameters such as temperature and humidity, can negatively affect agricultural quality and productivity, making it necessary to implement automation strategies that ensure stable environmental conditions. The proposed system uses an ESP32 microcontroller as the central control unit, integrating UV, temperature, humidity, and luminosity sensors, along with actuators for UV light regulation using a PID control algorithm, which allows the variable to be maintained within optimal ranges. In addition, a web dashboard is developed that offers real-time data visualization and remote interaction with the system, facilitating greenhouse management at scale.
