Estudo de módulos de comunicação sem fio.

Abstract

The word wireless is an English term whose meaning is "without wire". In recent years, the use of wireless networks has become popular, the idea of this type of communication, however, is not so recent. The popularization of wireless communication covers all fields, such as industrial, commercial or residential. The latter, in particular, automation applications have grown strongly. Currently, there is a wide variety of modules on the market that fulfill this function of "transporting" information from the distance. This work approached some of these modules, their characteristics and how they work, as well as some tests and applications to serve as a basis for those who wish to use them. It will also bring the study of electromechanical components used for these tests. These modules usually require a microcontroller to interpret the received information or, in many cases, to organize the information that will be sent. For this, the Arduino development board was used. The choice in each module should be made according to the needs of the desired application.
