IOT Based Smart Door Locked System Using Node MCU

Abstract

Abstract: People are experiencing more security issues around the world today, and security has become the most important concern everywhere in the world; as a result, security has become increasingly important in recent years. Security refers to the safeguarding of our lives and property. It is critical to ensure the safety of people and their valuables in order to prevent illicit handling. As a result, concentrating on door lock or gate security is critical to minimize more difficulties in the monitored area. The goal of this project was to create an internet-connected door lock that could be simply put on a variety of doors, operated via the internet, and trusted for security. Modern homes are gradually moving away from traditional switches and toward a centralized control system with remote control switches. A smartphone-controlled home automation system gives a modern answer. The most significant advantage of our proposed system is to build smart door lock which can be access remotely via mobile, to increase security of the house and to design and implement a cheap and open source home automation.This project will make human lives more versatile with enhanced security, ease, and the ability to live an upper-class lifestyle, resulting in our lives becoming much simpler, finer, accessible, and stable
