    Hydroponic green fodder consists of the production of plant biomass, regardless of the climatic limitations of the areas, resulting in the germination, growth and development of the seed in a time not exceeding 15 days, being a complement that provides a high value nutrition, vitamins and proteins to various animal species, considering itself as an organic farming solution to the excessive use of pesticides , promoting clean technologies and good agricultural practices, optimizing the proper use of spaces and thus guaranteeing the food security of the species. The present research work contemplates the analysis, design and implementation of an intelligent hydroponic system applied to the production of green fodder with IoT architecture, through the construction of a chapel-type greenhouse located on a flat surface, for the cultivation of oat fodder. The IoT system for forage cultivation is based on the Fog Computing architecture where sensors are grouped to take the physical and chemical variables of temperature, humidity, PH and total dissolved solids in the environment, irrigation actuators by misting, reduction of solutions and ventilation. The acquisition, conditioning and control of the signals of the different devices installed in the system are carried out on the Arduino development platform, which analyzes, processes and selects the data to be sent to the server through a microcontroller with Wi-Fi communication that serves as a gateway, which connects with the Arduino through serial communication and with the server through MQTT, thus obtaining the data flow bidirectionally for remote control and monitoring. The server hosts the “Home Assistant” automation software that provides an interface with statistical data from the sensors, control buttons and video images for real-time monitoring of the system. Allowing the hydrocultor to access from outside the local network for system remote control, report generation, history review, receive alerts and check status. The system helps to reduce the gap between the hydroculturists and the technological elements

    Sistema inteligente de monitoreo y vigilancia para plantaciones agrícolas de pitahaya en el cantón Palora basado en tecnologías IoT y LoRa
    (Universidad Técnica de Ambato. Facultad de Ingeniería en Sistemas, Electrónica e Industrial. Carrera de Ingeniería en Electrónica y Comunicaciones, 2022-09) Medina Vinueza, Leslie Dayan; Cuji Rodríguez, Julio Enrique
    The Internet of Things (IoT) focused on smart agriculture has made it possible to achieve great technological development in this sector through the development and implementation of a smart agriculture system for pitahaya plantations in the Palora canton, which will be installed to allow that pitahaya farmers have intelligent monitoring and proper management of their crops based on data from humidity sensors, soil pH level, C02, light and temperature. The main objective of this research work is the monitoring of soil variables in pitahaya plantations, taking data directly from the soil through two nodes that are bidirectional each one, they are composed of different stages. The first stage is the data acquisition in which an Arduino Uno was obtained to acquire the plantation information, then the node transmits this information through LoRa to a Gateway called the gateway stage, then the data they are sent to an internet connection device where the data is managed and printed through POST methods to the database managed with MySQL, finally for the design of the monitoring application, web development technologies such as HTML, PHP as backend were developed. , JavaScript and CSS. In addition, one of the nodes controls the irrigation of the plantation through a tank level sensor and solenoid valves that open or close, depending on the activity to be carried out. The sensors cover an approximate area of 10,000 square meters. The implementation of the monitoring system allowed the improvement and control of the soil through adequate monitoring at all times and in real time of the plantations, in addition the implementation of LoRa demonstrated to have a low-power and longrange wireless technology with the objective of identifying and reduce costs, improving pitahaya production and soil management.
