Abstract: Home security has grown to be a boosting issue in the current society and as such, there has been a necessity of affordable and effective security equipment to protect residential areas. In this paper, a smart home security system connected to the IoT is introduced and includes a laser module, ESP32 Nano, LDR sensor, buzzer, Telegram bot, and an electronic lock to identify intrusion and add more security. The system works based on an on-going scanning of a laser beam with the aid of an LDR sensor. Following the breakage of the laser path by an intruder, the LDR determines the disturbance and commands the ESP32 Nano to switch on the buzzer alarm, send an immediate notification through Telegram, and unlock the door automatically in order to inhibit illegal access. The application of IoT communication to the Telegram bot will guarantee that a homeowner can be alerted to any possible security breaches in real-time and respond adequately. The application of ESP32 Nano, which is a low-power microcontroller that has inbuilt Wi-Fi features, will make data processing efficient and also enable an easy remote communication with minimal power consumption. The design of the proposed system is aimed at being economically friendly to purchase and easy to install without requiring difficult wire connections or expensive hardware materials. It has a better automation, ability to have remote monitoring and ease of response as compared to traditional security systems. There is also the option of the very automatic locking that provides more layers of safety in reference to the intrusion security. The results indicate the system to be practical, reliable and scalable therefore making it a solution to consider in contemporary smart home setup. Additional visualization could be incorporated in the future such as camera support, AI support in motion mechanism, and cloud support in data storage to add more security and monitoring features.
