Prototipo de solución Iot con tecnología Lora en monitoreo de cultivos agrícolas

Abstract

This paper consists in the theoretical-practical development of a prototype IoT solution for the monitoring of agricultural crops, implementing a new technology in the IoT sector "LoRa", the account with low energy consumption and long distance 8Km in line of sight ) between the transmitting device and the receiver of the device, in order to know the physical variables that directly enter the process of a culture through a website. The acquisition of data from the sensors (temperature, humidity, radiation and Ph) have direct communication with the arduino system + LoRa shield, a this is determined as "NODE"; the node sends the data through LoRa communication to the respective Gateway (hub). The Gateway sends the data of each node to a public server called "thingspeak", this server has an "id" and "channel id" to determine which node is sending the information. The information found in each channel is connected through an "API key" that allows the implementation in the Visual Studio program of a Web Service. A relational database is designed in SQL Server, where the data is stored in an orderly manner for further processing, by means of stored procedures in SQL Server the respective processing of the information that is graphed in the web application is performed (Statistics, alerts, sensor data for each node). The web application has a suitable interface for the user that allows to visualize the information of the sensors of each node, real-time statistics and alerts when the measurements are not within the parameters that can be established by the same application. Then, is presented the development chapters including each of the tools used to reach the fulfillment of the objectives of the project raised, which are disclosed in Chapter 1, that presents the general introduction of the project and its scope. Chapter 2 is disclosed which involves the theoretical framework used as a reference each resource development. Chapter 3 shows the methodological process of developing the project. Chapter 4 shows the results obtained; and finally Chapter 5 provides the definitive conclusions found.
