In agriculture, water is vital for the crop. Knowing when to irrigate and how much to irrigate can be answered technically from data provided by weather stations. However, this data is not always available. In addition, although irrigation controllers are available on the market, they are not integrated with the stations and have a closed architecture. On the other hand, the development of electronics, the availability of affordable sensors, protocols, standards and open source, facilitate the integration of hardware and software components. This work proposes a prototype of an intelligent weather station that provides real-time data on temperature, ambient humidity, soil moisture, and rainfall, as input for a controller to activate irrigation in two cases: i) due to the need of water for crop development; or ii) to mitigate frost, supporting sustainable agricultural development with local, open source and affordable technology. The methodology was applied based on rapid prototyping, evaluating the operability of each electronic device and its integration in a controlled environment, and then in an experimental plot, at the Nero farm of the University of Cuenca. Open-source hardware and software were used for the development, using Arduino IDE and Visual Studio Code. A solar panel and batteries were used to power the system, optimizing consumption. This prototype has shown continuous and stable operation at 3100 meters over the sea level. It will continue to be monitored and improved, in order to make it available to the end user in the future.

The water and soil program PROMAS of the University of Cuenca contributes to the sustainable management of water and soil resources. To carry out this task, PROMAS requires, among others, to monitor environmental parameters using meteorological stations. In the present work, a rainfall data logger was developed on a compact printed circuit board (PCB) using surface mount components. LoRaWAN/ LoRa technology is used to transmit the information. LoRa is one of the LPWAN low power, long range network technologies. LoRaWAN is a protocol that manages end-to-end communication. This development integrates the acquisition, storage and transmission of data. The architecture is made up of a gateway device, the network server, and sensor nodes distributed over the area of interest. The data logger has the additional function of downloading data on-site using WiFi technology. The tests carried out showed that the developed prototype worked correctly in the acquisition, transmission and storage of data
Uso de imágenes de RPAS para generación de topografía a detalle

More and more, studies and medium-sized projects in many thematic are demanding more detailed topographical information (contour lines, digital elevation model). Obtaining this topography by traditional methods can be very costly in economic terms and take a long time. In this article, we present a method for obtaining not only orthophotos but also topography from images of Remotely Piloted Aircraft Systems (RPAS). We made emphasis about the advantages of RPAS over traditional methods for topographic in detail. RPAS can quickly to get high-resolution images and generate digital elevation models (DEM) or digital surface models (DSM) at low cost. The major issue of UAS is the ability to generate topography in detail or large-scale. This is due to the ability to fly at low altitude. This study follows the methodology of aerial photography and photogrammetry techniques to transform 2D models (aerial images) to 3D models (DEM and DSM). We show a case study to get topography (scale 1:1000 and contours lines 1m) of Irquis farm of University of Cuenca, Azuay province. We use an X8-M system to get aerial photographs. Finally, we validate those obtained cartographic products. The validation is based on technical standard for altimetry of Military Geographical Institute (IGM), which develops and provides official reference cartography of Ecuador. The results we obtained were satisfactory. Therefore, RPAS technology is important to consider getting not only orthophotos but also topography of medium-scale projects with accessible costs
