Nowadays, the chance of having an automated home is no longer a fancy luxury, but a reality accessible to a wide range of consumers, because smart home systems have replaced those that only automated the home in the past. More and more solutions based on IoT are being devel-oped to transform homes into smart ones, but the problem is that the benefits of home automa-tion are still not clear to everyone as they are not promoted enough, so we cannot talk about a broad mass of consumers already using integrated or DIY solutions to improve their lives. In this paper, I will present a home automation system using Arduino Uno integrated with rele-vant modules which are used to allow remote control of lights or fans, changes being made on the basis of different sensors data. The system is designed to be low cost and expandable, bring-ing accessibility, convenience and energy efficiency.
