Diseño de un sistema de control automático de la temperatura, humedad y riego de un vivero utilizando la tecnología IOT

Abstract

The objective of this study was to develop an automatic control system for temperature, humidity and irrigation of a nursery using IOT technology, to facilitate the administration, control of variables and in this way have better distributed irrigation and improve the quality of the plants. In the implementation of this project, 3 variables were controlled, which are humidity, temperature, and irrigation according to the programming in the controller. The method of irrigation by nebulization with the use of 4 solenoid valves that allow the passage of the fluid with on-off control, the feedback of the system is achieved through temperature and humidity sensors, distributed at specific points throughout the nursery. The data obtained by each of the sensors is analysed by a free-use embedded card (Arduino), which functions as the controller and is in charge of taking control action on the different actuators of the system. Also, an IOT ESP8266 communication module is integrated into the card. The use of IOT technology within automatic control serves as a tool for data analysis and to optimize manual processes. In this case, reduce the excessive use of water caused by conventional irrigation systems, additionally, the user can operate the system manually, observing the data recorded from the sensors within the IOT and activating it according to the required needs of each of the plants. It is recommended to use the irrigation system in various plantations
