Fingerprint Based Door Lock And Security System By Using Arduino

Basic System Flow:
Fingerprint Verification:
- Capture and store authorized fingerprints during system setup.
- Implement code to compare scanned fingerprints with stored fingerprints.
- If the fingerprint matches an authorized user, unlock the door.
Security System Activation/Deactivation:
- Use the button to toggle the security system on and off.
- When activated, the system should require fingerprint verification for door access.
PIR Sensor Integration:
- Monitor the PIR sensor to detect motion near the door.
- If motion is detected while the security system is activated, send an alert via SMS.
SMS Notifications:
- Implement code to send SMS notifications using the GSM module.
- Send a message when an invalid fingerprint is detected or when unauthorized access is attempted.
Logging and Status Indication:
- Log events and activities for future reference.
- Use LEDs or a display to indicate the current status of the system (e.g., armed, disarmed).
Programming:
Use the Arduino IDE to write and upload the code to the Arduino board.
Utilize appropriate libraries for the fingerprint sensor, PIR sensor, and GSM module.
Security Considerations:
Ensure that sensitive data, such as fingerprint templates, is securely stored.
Implement proper error handling and encryption mechanisms.
