Automatic Door Opening System Using RFID and Arduino System

Among the many potential applications of inexpensive radio frequency identification (RFID) technology are security, tracking assets, people monitoring, supply recognition, and access control. This project's principal objective is to design and develop a digital security system suitable for deployment in a restricted area that can only be accessed by authorized users. As part of our security system, we included a mechanism to lock the doors. The system is able to do the job because it uses RFID technology in conjunction with Arduino. The system obtains the user's unique identification (UID) and checks it against the stored UID when the RFID scanner at the entry detects an RFID tag. Access is given or refused based on whether the user's captured UID matches one of the stored UIDs. The system's three most important components are an electrical locking mechanism, an Arduino microcontroller, and an RFID reader module. The RFID reader will verify the card's validity, and then the Arduino microcontroller will use that information to start the lock. The results prove without a doubt that the system is an efficient, dependable, and cost-effective way to give or restrict access in a protected setting.
