OTP Based Door Security System with Email Verification – EEE Final Year Project

---

Introduction:

In an era where security is paramount, the development of innovative and reliable security systems has become a priority. Our OTP Based Door Security System with Email Verification offers a robust solution, combining the latest in microcontroller technology, sensor integration, and communication modules to ensure maximum security. This project is an excellent choice for EEE final year students, providing practical experience in designing and implementing advanced security systems.

Project Overview:

The OTP Based Door Security System is designed to provide secure and authorized access to premises. At its core, the system uses an Arduino UNO microcontroller to manage and coordinate various components, ensuring seamless operation. The system employs a combination of OTP (One-Time Password) and email verification for enhanced security, making unauthorized access virtually impossible.

Key Components and Their Functions:

1. Arduino UNO:
   • Role: The main microcontroller that manages the entire system.
   • Functionality: It processes input from the keypad, generates OTPs, communicates with the GSM module, and controls the relay module and LCD display.
2. SMPS 5V 5A:
   • Role: Power supply.
   • Functionality: Provides a stable and reliable power source to all components, ensuring consistent performance.
3. Keypad:
   • Role: User input.
   • Functionality: Allows users to enter the OTP for accessing the door. The keypad is crucial for interacting with the system and entering the correct password.
4. IR Sensor:
   • Role: Monitoring.
   • Functionality: Counts the number of people entering and exiting the premises. It enhances security by providing real-time data on movement through the door.
5. 3-Channel Relay Module:
   • Role: Control.
   • Functionality: Controls the signal lights (Red & Green) and the solenoid lock. The relay module ensures the correct operation of these components based on the microcontroller’s commands.
6. GSM Module:
   • Role: Communication.
   • Functionality: Facilitates communication with the user’s mobile phone for OTP generation and email verification. This module is essential for sending and receiving data.
7. Buzzer:
   • Role: Alert.
   • Functionality: Provides audio feedback for various states of the system, such as incorrect OTP entries or unauthorized access attempts.
8. LCD with I2C:
   • Role: Display.
   • Functionality: Shows the OTP entry process, status messages, and other relevant information to the user. It ensures the user is informed about the system’s state at all times.

How It Works:

1. User Initiation:
   • The user approaches the door and initiates the process by pressing a designated button or entering an initial code on the keypad.
2. OTP Generation and Email Verification:
   • The Arduino UNO generates an OTP and sends it to the user’s registered email via the GSM module.
   • The user retrieves the OTP from their email.
3. OTP Entry:
   • The user enters the OTP on the keypad.
   • The Arduino UNO verifies the entered OTP.
4. Access Control:
   • If the OTP is correct, the relay module activates the green light and disengages the solenoid lock, allowing the door to open.
   • If the OTP is incorrect, the system activates the buzzer and the red light, indicating an error.
5. Monitoring and Feedback:
   • The IR sensor counts the number of entries and exits, providing real-time monitoring.
   • The LCD displays the process and any error messages, keeping the user informed.

Advantages of the System:

1. Enhanced Security:
   • The combination of OTP and email verification ensures only authorized access, making it extremely difficult for unauthorized individuals to gain entry.
2. User-Friendly Interface:
   • The system is easy to use, with clear instructions displayed on the LCD and simple OTP entry via the keypad.
3. Real-Time Monitoring:
   • The IR sensor provides accurate and real-time data on the number of people entering and exiting, adding an extra layer of security.
4. Efficient Power Management:
   • The SMPS 5V 5A ensures that all components receive a stable power supply, maintaining the system’s reliability and performance.
5. Educational Value:
   • For EEE final year students, this project offers hands-on experience with Arduino programming, sensor integration, and communication modules, enhancing their practical skills and knowledge.

Applications:

1. Residential Security:
   • This system can be implemented in homes to ensure secure access, providing peace of mind for homeowners.
2. Office Access Control:
   • Businesses can use this system to control employee access to sensitive areas, ensuring that only authorized personnel can enter.
3. Educational Institutions:
   • Schools and colleges can use this system to monitor and control access to restricted areas, enhancing campus security.

Conclusion:

The OTP Based Door Security System with Email Verification is a state-of-the-art project that combines advanced technology to provide a secure and reliable access control solution. Ideal for EEE final year students, this project not only enhances security but also offers valuable learning experiences in modern electronic and communication systems. By integrating components such as the Arduino UNO, GSM module, and various sensors, this system represents a significant step forward in access control technology.
