Sistema de riego para invernaderos con interfaz web utilizando un arduino yun: adquisición de datos con arduino y yun.

Abstract

This final degree project deals with an irrigation system for greenhouses with a web interface using Arduino YUN platform. This component focuses specifically on the acquisition of the environmental parameters that influence the greenhouse such as temperature, humidity, and luminosity. For this, the Arduino UNO platform in conjunction with Dragino YUN shield were used, also sensors array that measures the environmental parameters, current/voltage meter modules INA3221 and the multiplexer TCA9548A. These last two work with I2C protocol. Concepts related to irrigation system, Arduino platform and sensors used are presented and what I2C protocol consist of. Moreover, the design of a system that integrates the sensors with the INA3221 module in a single device is presented. Also, an algorithm that manage the acquisition and organization of the data obtained from the sensors system to be evaluated within a controlled environment to observe the variation in the acquired parameters and probe its performance. To verify the correct acquisition of the data, specialized equipment to measure temperature, humidity and luminosity were used to calibrate the sensor used in this project and compare the data obtained with the proposed final model. Besides, I2C protocol was used in conjunction with a current/voltage meter modules INA3221 and multiplexer TCA9548A that work with this protocol to improve the efficiency use of the Arduino pins and make it a scalable system for the number of sensors
