Oct 13, 2025 by wbrum.org 114 views

Introduction

Door access security is a crucial aspect of maintaining safety and security in homes and offices. Conventional key systems, which are often easily duplicated, make them vulnerable to theft. To overcome this, the door security system integrated with modern technology such as RFID (Radio Frequency Identification) offers a more sophisticated and safe solution. In this article, we will discuss the design of a security system access open door using RFID and delivery of information to mobile.

The Need for Advanced Door Access Security

Traditional key systems have several limitations, including:

Easy duplication: Conventional keys can be easily duplicated, making them vulnerable to theft.
Key loss: If a key is lost or stolen, it can compromise the security of the door.
Key management: Managing multiple keys for different users can be a complex task.

To address these limitations, advanced door access security systems have been developed. These systems use modern technologies such as RFID, PIR sensors, and mobile notifications to provide a higher level of security and convenience.

Design of the RFID-Based Door Access System

The RFID-based door access system uses RFID and password as the main key to opening the door from outside. When the user closes the RFID card or enters the correct password, the system verifies their identity and provides access to the door. Meanwhile, to access the door from the inside, the PIR (Passive Infra Red) sensor functions to detect movement and automatically open the door.

Components of the System

The system consists of the following components:

RFID Reader: The RFID reader is responsible for detecting the presence of RFID tags with a maximum distance of 4 cm.
PIR Sensor: The PIR sensor detects unwanted movements and adds an additional layer of security.
Modem: The modem sends notifications to the owner's cellphone in the event of a theft experiment.
ATMEGA 8535 Microcontroller: The microcontroller processes all data and regulates all system operations.

How the System Works

Here's a step-by-step explanation of how the system works:

RFID Tag Detection: When a user approaches the door with an RFID tag, the RFID reader detects the presence of the tag.
Verification: The system verifies the user's identity by checking the RFID tag against a database of authorized users.
Access Grant: If the user is authorized, the system grants access to the door.
PIR Sensor Detection: When a user approaches the door from the inside, the PIR sensor detects movement and automatically opens the door.
Notification: In the event of a theft experiment, the modem sends a notification to the owner's cellphone with detailed information about the events that occurred.

Benefits of the RFID-Based Door Access System

The RFID-based door access system offers several benefits, including:

Higher Security: The system provides a higher level of security compared to conventional keys because RFID tags are difficult to duplicate.
Convenience: The system allows users to access the door without the need for physical keys.
Real-time Notifications: The system provides real-time notifications to the owner's cellphone in the event of a theft experiment.

Conclusion

The RFID-based door access system is a practical and safe solution to improve home or office safety. By using the latest technology, this system offers better protection and guarantees calm for users. The system's advanced features, including RFID tag detection, PIR sensor detection, and mobile notifications, make it an ideal solution for homes and offices that require high levels of security and convenience.

Future Work

Future work on this project could include:

Improving the System's Accuracy: Improving the system's accuracy by reducing false positives and false negatives.
Adding Additional Features: Adding additional features, such as biometric authentication and video surveillance.
Scalability: Scaling the system to accommodate larger numbers of users and doors.
