Diseño para análisis y estimación de humedad de suelo mediante técnica Kriging y WSN

Abstract

Considering the importance of water resources, as an essential element that throughout the development of agriculture, has conditioned its production and has required the development of new techniques for its control and use. It is this concept that lays the basis for this research, where a series of parameters are proposed for the design of a WSN network, whose main focus is soil moisture analysis based on Kriging geostatistical interpolation, in order to generate a tool for farmers to make decisions in the design and implementation of irrigation systems. Seeking this objective, a detailed study of the optimal location of sensors is carried out using the repetition technique and humidity estimation, in order to achieve a structured design, which is based on mathematical principles to solve an important optimization problem in WSN networks (Wireless Sensor Network), as is the location of the sensor nodes. In turn, on the line of soil moisture characteristics research, the calibration of the DFROBOT Capacitive Soil Moisture Sensor (V0.3) moisture sensor is supported by means of the gravimetric method, as a precise means for obtaining experimental samples. , compatible with the Arduino platform. On the other hand, giving support for the future real implementation, it is suggested through research and tests, the Zigbee communication protocol, for the implementation of the sensor network architecture, adjusting the use of Arduino as a micro-controlled system for data conversion and transmission.
