DESIGN AND MANUFACTURE OF AN IOT

Security is a very important part of any organizations structure. The modern age comes with an increasing need for secure and flexible access control systems. This project designs and implements a Radio Frequency Identification security door lock system. It features a mobile application is also built to control the system and manage user accounts and permissions. Wi-Fi connectivity is implemented to enhance access control. The limitations of traditional lock systems is the major motivation behind this project. Although noteworthy achievements have been made
in this field, there is still a lot that can be improved upon. This project utilizes the ESP32 microcontroller, RFID reader module, electronic bolt lock as the primary components. This system primarily authenticates users with the use of Radio Frequency Identification (RFID) tags. The application also servers as a secondary access option when needed.
The application is used to control and manage users and cards. Role based access makes it possible for different user roles to have different levels of authority over the system. User and card information are stored in a PostgreSQL database which makes it easy to manage the system from different locations. The system also possesses a battery system as a source of alternative power in the event of power outages. This project takes an Internet of Things (IOT) approach to RFID security and connects the lock hardware and software seamlessly to make the system more efficient, flexible and robust. The system is tested to approximate its behavior in a real-life situation before it is installed. The tests proves that the system is an improvement in efficiency, ease of use and flexibility in access control and security. There are a lot of other opportunities that could be explored that would further improve the systems performance but are beyond the scope of this project work and are suggested in the recommendations for future work.
