Abstract
In today’s world, more than ever before, we are fascinated and drawn towards smart autonomous devices that make our lives safer and more comfortable. Devices that aid in reducing our energy consumption are also highly appreciated but often quite expensive to buy. This context is favorable for developing an autonomous smart home automation system (SHAS) with energy-saving potential and low price, making it widely accessible. This paper presents the design and prototype implementation of such a low-cost micro-controller based autonomous SHAS that learns the resident’s work schedule and integrates a wide array of sensors and actuators to automatically control the lights, temperature, humidity and power sockets. The proposed automation system also monitors the home environment for potential energy-saving opportunities, gas leaks, or unauthorized entry. For reliability purposes and to limit the risk of signal interference, the proposed system design uses a wired inter-module communication method. To enhance the home’s security, both personal identification number (PIN) protection and Global System for Mobile Communications (GSM) communication are added, making the proposed system design less vulnerable to cyber-attacks when compared to other wireless alternatives. The hardware and software architectures, the prototype test results and the cost analysis are presented in detail, validating the system’s design and efficient operation as an autonomous smart home automation system.

Summary
Aiming to improve our safety and quality of life, automation systems found their way into our homes for several years now. By integrating new technologies and intelligent control algorithms, smart home automation systems have the potential to improve home security, safety and comfort while reducing the home’s energy consumption if energy management functions are integrated into the system. The available statistic data shows that about 40% of the energy consumption of the United States of America was recorded in residential buildings in the year 2017 [3] while, according to Eurostat [4], during the same year, European residential buildings recorded around 27% of continent’s energy consumption These values are significant, so new technologies that have the potential to reduce our home energy consumption are highly relevant in today’s world. One of the most affordable SHAS was designed, built and tested, with this paper presenting the laboratory test results
