Sistema de automação residencial com ênfase em segurança e economia energética

Abstract

Considering the diversity of solutions in home automation and security this research seeks the implementation of a home automation system that aims to improve the energy efficiency, make home surveillance and have low investments. This system provides the following functionalities: alert the presence of intruders and automation of air conditioners. When a presence is detected a notification is sent to an application installed on an android or IOS device containing the link for an webcam and push buttons that can activate a siren. The air conditioner is controlled by schedule or manually and will be provided automatic calculation of its kWh weekly. To decrease expenses an open source software called Home Assistant, which can be remotely controlled, was embed in the Raspberry pi microcontroller, the number of sensors was reduced to only a PIR presence sensor, an infrared sensor, for controlling the air conditioner, and a webcam, for local surveillance. The software tests conducted on the system reveal that the execution of the software and its functions meet the requirements of reliability and security, the hardware tests with the prototype comply with this project objectives while having low implementation costs. The observed performance is comparable to a professional home automation system.
