Abstract:  In the era of smart homes and IoT (Internet of Things), traditional doorbell systems are evolving to offer enhanced convenience, security, and real-time communication. This paper presents the design and implementation of a Smart Doorbell System utilizing an Infrared (IR) sensor and the ESP8266 Wi-Fi module, integrated with the Blynk mobile application for instant notifications. The system detects the presence of a person near the entrance using the IR sensor and immediately triggers the ESP8266 to send a push notification to the user's smartphone via the Blynk cloud platform. The proposed system is cost-effective, easy to install, and provides real-time alerts without the need for physical interaction, enhancing security and user experience. This approach not only eliminates the limitations of conventional doorbells but also demonstrates the potential of integrating microcontrollers with IoT platforms for smart home automation. The implementation and testing results confirm the system's effectiveness in timely notifications, low power consumption, and reliable connectivity, making it a practical solution for modern home security.

Keywords:  IoT, ESP8266, Infrared Sensor, Blynk, Smart Home, Wireless Notification.
