Desenvolvimento de um sistema de alarme residencial com acionamento remoto de cargas

Abstract

The lack of security is one of the main problems faced by the Brazilian population. Thus, an increasing number of consumers are looking for home security solutions, contributing to the growth of the sector responsible for the development of security systems, in addition to home automation that is also known as home automation. As much as these systems have been improved over the last few years, they are still not accessible to a large part of the population due to the difficulty in implantation and, mainly, due to the high cost related to the acquisition of the devices, labor and infrastructure necessary for the correct functioning of the system. Thus, it is essential to develop security systems that have a reduced cost and wireless communication. The present work proposes the development of a prototype of a low cost microcontrolled residential alarm system, with remote load activation capability, wireless communication between the central and sensors / actuators, reducing the adversities with infrastructure for installing the devices. However, the system must meet all the essential requirements of an alarm system, ensuring the safety of the environment where it is installed. The system's functionality and reliability were proven through experiments carried out in a controlled environment, where sensors / actuators were installed about 30m from the plant, whose communication took place satisfactorily, as expected.
