Development and implementation of a smart greenhouse

Abstract

A smart greenhouse was developed at Laboratorio de Informatica Aplicada with the department of Agronomic Engineering at the University of Rio Negro, it must provide real-time measurements of parameters such as humidity, temperature and luminosity; it also must allow manual and automatic control for actuators such as heaters, sprinklers and fans based on user input. In order to fulfill the aforementioned requirements the following actions were performed: (a) Design and implementation of a webpage to communicate with and control the greenhouse and, (b) Development: at first a model using Object Oriented Programming was implemented in an Arduino Mega board equipped with an ethernet shield; posteriorly, given that Arduino could not fulfill the necessary tasks, it was decided to develop a second prototype using a Raspberry Pi 2 Model B+ board along with completely new software programmed in Python 3.
