Seamless Home Automation: Integrated Smart Security and Comfort Systems

Abstract

Introduction: Traditional home security systems often lack the capability for real-time remote monitoring, intelligent control, and timely alerts, making them vulnerable to break-ins and delays in emergency response. With the rise in smart home adoption and the need for affordable, automated solutions, the limitations of conventional door lock systems have become more evident. The growing demand emphasizes the need for a user-friendly, IoT-integrated system that enables efficient, secure, and responsive home protection.

Objectives: The primary objective of this project was to design and implement an IoT-based smart door locking system that combines real-time image monitoring, motion sensing, and remote control functionalities. The system aimed to enhance security, enable user interaction via a Telegram bot, and ensure energy efficiency through intelligent automation using low-cost and easily available components. The final goal was to deliver a cost-effective, reliable, and scalable smart home solution

Methods: The methodology of this project involves the systematic design, development, and testing of an IoT-enabled smart door lock system using ESP32 and related components. The process begins with hardware selection, where key components such as the ESP32-CAM module, solenoid lock, relay module, PIR motion sensor, and power supply units are chosen for their affordability, ease of use, and compatibility. The ESP32-CAM is programmed to connect to Wi-Fi and communicate with a Telegram bot, acting as the core controller for image capture and communication functions. The solenoid lock is controlled through a relay module, which acts as an electronic switch triggered by the ESP32-CAM based on commands received via Telegram.

Results: The experimental evaluation of the SecureShield smart door lock system demonstrated significant enhancements in home security through multiple integrated technologies. Real-time visual tracking via the ESP32-CAM enabled prompt image capture and transmission, providing users with immediate remote verification through the Telegram bot interface. The laser-based intrusion detection system successfully differentiated between legitimate access attempts and false alarms, ensuring reliable security monitoring.

Conclusions: In conclusion, the proposed smart door lock system using ESP32-CAM, solenoid lock, relay, and sensors offers an effective and affordable solution for home security. By integrating Telegram for communication, it enables real-time image capture, remote control, and motion detection alerts, enhancing user convenience and safety. The system’s design balances functionality with cost-effectiveness, making advanced home automation accessible to a wider audience. This project highlights how IoT technologies can be harnessed to deliver reliable, user-friendly security solutions that surpass many existing commercial options.
