Diseño e implementación de un sistema IoT de supervisión y control de parámetros químicos del ambiente en un galpón de una planta avícola de Licto.

Abstract

This curricular integration research project aimed to design and implement a system with Internet of Things (IoT) technology for the supervision and control of chemical parameters of the environment in a shed of a poultry plant in Licto, for which it was designed a central board, two data acquisition node cards, a push button panel, and a mobile application. The chemical parameters controlled are temperature and ammonia levels. The central board has an Arduino Mega Pro Mini development board which receives the information from the acquisition nodes; it has a SIM800L in charge of sending the data to the mobile application through IoT. The acquisition nodes have an Arduino Nano and the following sensors: temperature, ammonia, and light, which are in charge of evaluating the environment of the shed. The central board and the acquisition nodes have radio frequency communication to send and receive information. A motor was implemented to open and close the curtains to ventilate the shed. The supervision was implemented through a mobile application with essential features that will help visualize the data from the sensors in real-time. Validation and repeatability tests of each sensor were carried out to record real data and perform various tests for the supervision and control of the system. Based on the results, it is concluded that the IoT system for the supervision and control of chemical parameters of the environment of a shed in the Licto poultry plant meets all the objectives, providing a high level of reliability in its operation. However, it is recommended to implement a human-machine interface (HMI) screen to improve user-system interaction.
