Smart advertising system with Raspberry PI3, Android application and free hardware

Abstract

The Peniel Church located in Guayaquil, Ecuador has several events of great importance for the people who come to it. However, the absence of a specific and highly visible place for publications means that people are not kept informed and up-to-date with the events that are about to take place. The objective is to design and implement an information system for the Peniel church, based on the use of Raspberry Pi 3, ESP32 microcontroller, keyboard and GSM module. In addition, it will incorporate a computer application to view the events through the cell phone. The research was carried out in the period from October 2019 to November 2020. Its scope is descriptive, with a quantitative approach and experimental design. The main scientific methods used are documentary analysis, observation, experimentation, analysis-synthesis and inductive-deductive. In addition, the ethics of Do It Yourself is used. Some tools and technologies used were Python as a programming language, Android Studio as an integrated development environment, and MongoDB as a database system. As a result, an information system was obtained for the Peniel church, which allows the events to be viewed through the cell phone, by means of a computer application. For this, a Raspberry Pi 3, an ESP32 microcontroller and a GSM module are efficiently used. Likewise, the proposal is based on the use of free hardware and software and constitutes an option with high performance, low cost and consumption.
