Implementation of Smart Home Automation System

The Internet of Things is a network of physical objects embedded using electronics, sensors, and programmed using software to establish connectivity and provide communication by exchanging data with users, manufacturers, and other IoT devices. Interconnected smart devices have become a ubiquitous part of daily lives. Innovative applications like smart home environments are incorporated into daily life with the increasing popularity of IoT, to improve convenience, comfort, energy efficiency, and safety. This paper presents a smart home automation system. In this work, the proposed smart home is initially simulated using the Tinkercad platform and later verified by hardware analysis. Smart home automation is efficiently achieved using various components with an Arduino Uno as a central controller which is integrated with various sensors (ultrasonic sensors to detect distance, PIR sensors to monitor the human presence, LDR sensors to adjust lighting, and smoke detectors to ensure fire safety) and other components like relays, transistors to manage high and low power devices, LEDs, push buttons to offer user control and feedback, and lights, buzzers, DC motors, servo motors to provide automation and mechanical movements.
