Abstract:
The creation of novel solutions like RFID-based smart locks has been fueled by the growing need
for automated and secure access control systems in residences, workplaces, and other
establishments. Lock picking, key duplication, and tampering are just a few of the security threats
associated with traditional locks, which are operated by physical keys. Moreover, these traditional
systems are unable to notify users in real time of any unwanted access attempts, which leaves people
and property at risk. This project focuses on designing and implementing a smart door lock system
that employs GSM connection and RFID technology to transmit real-time alerts when entry is
denied in order to address these problems. The core of the system is an Arduino microcontroller,
which acts as the main control module. By determining if an RFID card or tag is authorized, it
processes data from the RFID reader to authenticate users. The door is unlocked by the system if
the user is authenticated. But in the event that someone not allowed tries to open the door, the
system sets off the GSM module to instantly notify the property owner or security staff by SMS of
the security breach. This instant alert makes it possible to act quickly, greatly enhancing the security
system's efficacy.
Compared to conventional key-based locks, the RFID door lock system is more reliable and
convenient in addition to offering real-time notifications. By doing away with physical keys—which
are more prone to theft, loss, or duplication RFID cards improve security. In addition, the system is
built to function independently, reducing the need for human involvement and guaranteeing safe
and easy access management. The addition of GSM technology expands the capabilities of the
system by offering remote monitoring a feature that is very helpful for security staff, company
owners, and homeowners. This guarantees that even in the event that the property owner is not
physically present, security breaches can be quickly identified and addressed. In addition to being
affordable, the system's accessibility benefits a broad spectrum of users, including institutions,
enterprises, and homeowners.
This smart door lock technology has a big impact on society. By limiting illegal entry and lowering
the possibility of security incidents like theft or incursion, it improves the safety of properties. This
system offers a dependable, effective, and expandable solution for settings where security is of the
utmost importance, like residences, workplaces, hotels, and medical facilities. The RFID door lock
with message alert system offers real-time alerts and addresses the shortcomings of conventional
locks, making it a contemporary and useful solution for enhancing security in today's hectic world.
