Projeto de um sistema de reencaminhamento de chamadas de interfone para dispositivos móveis.

Abstract

The creation of this project was based on the development of a system that makes use of several technologies and, consequently, for its accomplishment a mobile application was developed for the Android operating system and another one that uses the hardware of a microprocessor with embedded software. The purpose of the system is to establish a communication between a residential intercom and the resident's smartphone. The microprocessor used was a Raspberry Pi 3 model B programmed with a Python language algorithm and the mobile application built with the Android Studio tool, using the Java language. When launching the intercom, the embedded device will create a means of communication with the smartphone through an online database, Firebase. At the end of the project, with its implementation implemented, a limitation was observed. When capturing the voice of the person standing in front of the intercom, a voice recognition library is used, and if there is too much ambient noise, recognition may fail.
