Se desarrolló en la Escuela Profesional de Ingeniería Electrónica de la Universidad Privada de Tacna, en la Carrera Profesional de Ingeniería Electrónica, y se trabajó con 55 estudiantes de todos los ciclos, matriculados en el programa. Se aplicaron dos instrumentos, una encuesta con una escala tipo Likert para establecer el desarrollo del portafolio de aprendizaje, y una encuesta con una escala tipo Likert para determinar el logro del perfil de egreso. Resultados: El valor del coeficiente de correlación R de Pearson obtenido es 0.905, que indica un nivel de correlación alta, entonces se establece que existe relación directa entre portafolio de aprendizaje y el lo...

Este estudio, consiste en el diseño de un prototipo, capaz de realizar el proceso de embotellado de yogurt. Basado en una estructura lineal; el prototipo de embotellado utiliza un Controlador Lógico Programable (PLC) que trabaja de manera automática consta de entradas y salidas, sensores de proximidad, válvulas, electroválvulas, luces piloto, cilindros neumáticos, un variador de velocidad que actúa a su vez como un ordenador secundario que gobierna la velocidad de revolución del motor que se encarga en ejecutar el transporte de botellas mediante una faja transportadora. Últimamente, la operación de arranque y paro de la maquina se lleva a cabo con una HMI (Human-Machine Interface) y pulsadores. Se probó y se puso en funcionamiento el prototipo de embotellado. Consiguiendo resultados que demuestran que se puede ampliar la producción y comprimir pérdidas en el transcurso de em...

Agriculture 4.0 incorporates information and communication technologies such as the Internet of Things (IoT), databases and smartphone applications. Greenhouse farming, at the same time, allows a rational use of water resources and a greater production in smaller cultivation areas. The increase in productivity generates the right conditions to ensure the nourishment of populations in the near future. The research presents a proposal for an IoT system to monitor and control parameters inherent to greenhouse crops based on the ESP32 microcontroller, using sensor nodes to collect data on temperature, relative humidity, soil moisture, as well as water level for irrigation. Using the ESP-NOW wireless communication protocol, the sensor nodes send the information to the central node. The central node activates and deactivates the actuators to control the climatic parameters and saves the inform...

The objective of this research was design an access network with FTTH technology to distribute broadband services in Gregorio Albarracín Lanchipa district, in Tacna. The technical characteristics and benefits of FTTH technology with the GPON standard are described. This research work aims to propose a solution to the problem of last mile access to the district's telecommunications services, 3034 users or subscribers located in the housing associations of the Viñani pampas are selected. This external plant network consists of the distribution network, access network and termination network architecture, as well as the supply network from the internet provider. A mapping was carried out to collect information regarding the location of the network of electricity distribution poles and thus to know the location of the ADSS fiber optic cable route in the district, location of the optical di...

Aquaponics, a practice that combines aquaculture and hydroponics, offers a sustainable alternative for food production in areas with limited water resources, such as some regions of Peru. However, properly managing water parameters, which are essential to maintain the system's balance, remains a significant challenge. In this context, the study aimed to design and implement a remote monitoring system based on IoT to measure and control critical water parameters in an aquaponic fish farm in Tacna, Peru. The methodology included the development of a hardware infrastructure with pH, turbidity, temperature, and water level sensors, connected to an ESP32 LilyGO microcontroller with MQTT communication and equipped with a GSM/3G modem (SIM7000G). Additionally, software was designed for data collection, transmission, and cloud storage, enabling real-time monitoring and automated actions. The res...

In order to evaluate the post-harvest behavior of climacteric fruits, an experimental team was constructed to determine the intensity of respiratory rate in parts per million (ppm) of carbon dioxide (CO2) per unit of mass and time, for which purpose they were used : a K-33ICB sensor for CO2 measurement; Thomas 2000DV / 0,5 / E / LC air pump; a glass water trap with a diameter of 2.5 cm and a useful length of 6 cm; a 0.22 μm hydrophobic filter; a 150 μm particle filter; a breathing chamber with a volume of 5.0 x10-3 m3 constructed of glass with two tabulations for gas exchange and latex ducts. The Gaslab ® software was used to acquire data. In order to evaluate the equipment, Hass avocado fruits (Persea americana) were selected in the degree of physiological maturity with 8.26% of oil, then conditioned in the breathing chamber with an initial weight of one kilogram, then sealed hermeti...

Landslides, triggered by heavy rains, constitute globally impactful natural disasters that wreak havoc on both people and infrastructure. It is crucial to develop predictive systems and efficient alerts, incorporating technologies such as the Internet of Things (IoT) to gather environmental data and prevent significant losses. Therefore, the aim of the study was to design and develop an early warning system for landslides using a microcontroller-based wireless sensor network. A digital rocker rain gauge and the MPU 6050, DHT22 and FC-28 sensors were employed. These sensors were distributed at nodes along the Quebrada del Diablo in the city of Tacna. The values captured at each node were processed by the DEVKIT V1 NodeMCU-32 development board, based on the ESP32 microcontroller, and transmitted to a central node through a ZigBee mesh network using Digi's XBee3 devices. The central node wa...

Climate change directly affects crops worldwide, posing an increasing threat to agricultural production and food security. The aim of this study was to design an Internet of Things (IoT) station to monitor microclimates and soil conditions. A system was implemented consisting of central nodes (ESP32 LILYGO T-SIM7000G with the RF module nRF24L01) and secondary nodes (NodeMCU-32, based on the ESP32 microcontroller), equipped with sensors to measure environmental and soil variables such as humidity, temperature, pressure, UV radiation, wind speed, as well as conductivity, nitrogen, phosphorus, and potassium. The devices used included a digital rain gauge MS-WH-SP-RG, a BME 280 sensor, an NPK soil sensor JXBS-3001-NPK-RS, a UV sensor CJMCU-GUVA-S12SD, an anemometer JL-FS2, and a weather vane B08N52YR8Z.
