Implementación de un prototipo con SoC para control de invernadero mediante comunicación LoRa.

Abstract

The implementation of an SoC-based prototype for greenhouse control, using LoRa communication and a web interface, offers an innovative solution. LoRa technology enables monitoring of devices over long distances with low power consumption, allowing users to remotely monitor their greenhouses without the need to be physically present. The system is structured around three fundamental pillars: the first focuses on a slave SoC that reads the environmental parameters from the sensors and controls the irrigation system, activating or deactivating it as necessary. The second pillar consists of bidirectional communication between two SoCs using LoRa technology, allowing the exchange of information between them. The third pillar involves a master SoC that receives data from the slave SoC via LoRa and transmits it to an IoT platform via a WiFi connection, where a control panel is available to monitor the data. Additionally, this master device also sends data via LoRa to activate the irrigation system. In the first section, the objectives were established, and the scope of the project was defined. In addition, the essential concepts for its development framework were detailed. The second section describes in detail the methodology used to achieve the previously established objectives. The third section presents the results obtained during the development of the project. The project requirements, component selection, code design for SoC programming, and their integration with Adafruit IO are addressed. The fourth section highlights the implementation and validation of the system through testing on a model. These tests focus on monitoring environmental parameters and soil moisture, as well as controlling an irrigation system. Finally, in the last section the conclusions of the project are presented, highlighting the effectiveness of the system. Recommendations and bibliographical references are also included. The annexes contain the source code and a video demonstrating how it works.
