Control de las soluciones y variables ambientales de un cultivo hidropónico de lechuga mediante un sistema embebido conectado a Internet

Abstract

This document presents the description of a project that aims to implement an electronic control system which controls environmental variables and nutritional solutions of a hydroponic crop on a small scale. The type of control to use is a classic PID control which will be implemented digitally through an embedded system, in this case a microcontroller that will be connected to the internet network.

As it is currently the trend to connect everyday objects to the internet, it is possible to monitor almost any object that you want, in this case a hydroponic crop. The system operator will have the possibility to observe the system variables through a web server connected to a local network.

The system proposed in this document is implemented by means of a prototype with an area no larger than 6 m2, so it is small in scale, however, being a development project, it has a greater projection as the project evolves. The final objective is to demonstrate that multiple variables of a hydroponic crop can be controlled and monitored, generating a great advantage to the farmer or anyone who wishes to undertake in the field of agronomy.

Currently, most of the world's farmers do not have the ease of accessing technologies that simplify mass cultivation and obtain high-quality products because many of the commercial systems are often very expensive or complicated to implement. This project demonstrates that it is possible to get a tool that is easy to acquire and at a low cost that can help in the area of ​​agriculture, especially those who do not have experience in this area.
