IoT-Based Electronic Door Opening System Using NodeMCU

Abstract: As the need for smart home automation continues to rise, the incorporation of Internet of Things (IoT) technologies into security systems is now a necessity. This paper discusses the design and development of an IoT-based electronic door-opening system using NodeMCU, a widely used microcontroller. The system is designed to offer secure and remote control of door operations through a web-based application, enabling users to control and monitor door security remotely. Through the integration of NodeMCU and IoT, the system improves conventional door security by facilitating real-time monitoring, access control, and remote control. The system discusses hardware and software components of the system, such as the microcontroller, sensors, and user interface. The paper also explains the system development methodology with major focus areas like connectivity, security protocol, and convenience to the user. The designed IoT-based door-opening system provides a cost-effective, expandable, and human-friendly solution to current security issues with simplicity of use coupled with increased security.
