Diseño e implementación de un prototipo IoT de supervisión y adquisición de datos aplicado a la jardinería domestica mediante una aplicación móvil.

Abstract

The objective of this curricular integration work was the design and implementation of a prototype for supervision and data acquisition applied to home gardening through a mobile application, to do that, a central card and two data acquisition node cards a power supply with solar cells and a mobile application were designed. The chemical parameters that are controlled are: temperature, humidity. pH and lighting. The central card has an ESP32 development card which receives information from the acquisition nodes, it has SIM80OL responsible for sending the data to the mobile application through IoT” The acquisition nodes have an ESP32 card, and he following sensors: temperature, humidity, pH and light, which are responsible for evaluating the domestic garden environment. The central card and the acquisition nodes have radio frequency communication to send and receive information. The monitoring of the home garden was implemented through a mobile application which has essential characteristics that will help visualize the data from the sensors in real time. Validation and repeatability tests were carried out on each sensor in order to be able to record real data, in addition to carrying out various tests for the supervision and control of the system. Based om the result, it is concluded that the prototype of supervision and data acquisition applied to home gardening through a mobile application meets all the objectives, providing a high level of reliability in its operation. However, it is recommended to implement a screen for human machine interface (HMI) in order to improve user-system interaction.
