Sistema modular de telemetría para medición de parámetros en el hogar, basado en el internet de las cosas

In this article, we discuss the development and results obtained in the design of a modular telemetry system for measurement of different parameters at home and having the possibility of knowing and monitoring the data remotely through a mobile application. Using instrumentation, it is planned to measure electrical energy consumed at home in kWh, the amount of water consumed, pressure and presence of LP gas, interior lighting, temperature and the energy generated by a photovoltaic panel interconnected to the electrical grid. The architecture proposed for the development of this application is based on the three-layer model of the IoT (Internet of Things), making use of a microcontroller based on the ESP8266 chip called NodeMCU®, the reading of the parameters proposed above is performed, and these data are transmitted through a Wi-Fi (Wireless Fidelity) communication protocol called Websockets®, the data is sent to a database on the internet using Firebase® service, later this database communicates with a mobile application in which displays the data collected by the microcontroller in a graphical interface programmed with Android Studio®. The user will be able to monitor the different parameters in real-time and based on his criteria, take preventive and corrective actions for the conscious use of his energy resources.

Generación de mapas climatológicos mediante el desarrollo de una estación meteorológica automática móvil

Agricultural studies present a common constraint in making decisions based on meteorological data, since climate models lack precise values of their parameters depending on the geographical point where information is acquired, so that weather acquisition in positions specific geographical results is an interesting possibility. The objective of the present study was to develop a mobile automatic weather station (AWS) with sensors that measure the air temperature (° C), the relative humidity of the air (%), the global solar radiation (Wm2), the wind speed (m/s) ) and the concentration of carbon dioxide (ppm); the sensors were connected to a controller medium to which they were incorporated: a real-time clock to adapt the acquisition intervals, a display to show the information to the user, a storage module for the acquired data, a module for remote transmission of the data and a global positioning system. In addition, the mobile unit contains a chassis, four wheels with their respective electric motors, power stage, two servomotors, two ultrasonic sensors and the general electrical power that give autonomy in their movement dynamics. The climate map of a polygon of 120m2 was obtained.

Alarma digital con sensor de movimiento

The insecurity that the homes of the communities of Jilotepec present in the face of robberies to the homes of families with low purchasing power, and the high prices of the security systems offered by specialized companies, the project of making a digital alarm through a motion sensor that detects intruders in the room. It has been developed through the CDIO methodology (Conception, Design, Implementation and operation) the Arduino platform was used, which in recent years has taken a lot of strength for the realization of engineering projects, as well as the PIR motion sensor HC-SR501, which has a low cost. The system can detect any movement, this with the help of people's body heat, informing the user about the activity that exists in their homes. Therefore, it will help people to have the system that makes them feel protected, especially at night.

Estructura tecnológica y organizacional de inclusión a la industria 4.0 en universidades como un factor en la eficiencia de procesos productivos y de servicios en el sector empresarial

Currently, society lives governed by technology, which evolves day by day, an example of this is the transformation represented by the last indicated Industry 4.0 paradigm. This concept is oriented to fulfill two main objectives; automation in the improvement of industrial processes; and device interconnectivity, where techniques such as sensing, and data analysis are used. Based on these tools, this technological transformation demands the study of industrial processes, or services, to identify key points in them where improvements can be made. Before implementation, these changes are visualized through scientific prototypes that have applied technology to predict their functionality in a real environment. These prototyping challenges create the perfect link between school and industry, as the latter need to improve research center support processes, such as links at universities. This article describes a flexible structure and methodology, designed for universities, to develop studies on processes in organizations and generate prototypes based on Industry 4.0 technology, from a scientific research perspective.

Uso de la arquitectura de mini servicios: gestión de servicios

There are various architectures that allow a distributed system that have been extensively tested in a business environment, with the purpose of having high availability. This infrastructure allows us a rapid deployment and a lower load on the network, rapid development among others. The present work aims to build software modules for a mini-service architecture, under a REST API managed by NestJs, sharing a Mongo database. General Objective: Implement the use of the architecture of miniservices in the development of the modules of resource management, control and monitoring of projects for the linking system between TecNM incubators and society in general. Specific: 1. Represent the processes using BPMN (Business Management Process). 2. Analyze the functional requirements of the resource module and service monitoring. 3. Design the architecture of miniservices. 4. Design the mini-services for the management of the resource module database and service monitoring. 5. Develop the mini-service for managing the resource module database and service monitoring. 6. Develop the mini-service for the management of the resource module and service monitoring. Methodology. To carry out this project, the SCRUM methodology is used, since for its development the participants were divided into two teams, due to the extension of the computer system. And SCRUM is characterized by offering a methodological framework of work that allows managing collaboration between various teams. As well as offering great adaptability to modifications on designs or previous coding, a very important point in this case, since we are working on a topic that is current and there is no previous experience, which generates constant tests and changes. SCRUM has another essential characteristic in this development, that it is designed for projects with a high level of uncertainty, as is our case, where the architecture of miniservices will be tested and the degree of improvements it provides will be identified. For all the above, this work has been carried out following the stages set by SCRUM, namely: 1.- Sprint planning. 2.- Stage of development. 3.- Sprint review. 4.- Feedback. Contribution. With this work, experience is provided in the configuration of an architecture that supports rapid development, decoupled, reusable and with the possibility of migrating to a microservice architecture..
