Door Lock Prototype Design Using A Fingerprint Sensor And Keypad System With A Buzzer -based Arduino Uno Warning
Introduction
In today's world, security is a top priority, and door locks are no exception. A door lock prototype has been designed using a fingerprint sensor and a keypad system equipped with Arduino Uno-based warning. This innovative design aims to increase door safety and provide a comprehensive solution for maintaining door security.
Design Overview
The door lock prototype uses a FPM 10A fingerprint sensor, which functions to detect user fingerprints. In addition, the keypad system is added as an alternative way to unlock, especially when the user's hand is wet or there are other disorders. The unique feature of this prototype is the buzzer, which will sound as a warning system if the user enters the password on the keypad. The buzzer will be active according to the regulated time, notification that there is an error during the key opening process.
Components Used
- FPM 10A fingerprint sensor
- Keypad system
- Arduino Uno
- Buzzer
- Doorlock solenoid
- Relay control
- Current voltage
How it Works
When someone wants to open the door, they simply put their fingers on the fingerprint sensor. If a detected fingerprint matches the data that has been registered in the Arduino program, the door will open and the LCD screen will display the "Door Unlocked" message. However, if the fingerprints used are not registered, the sensor will not respond because there is no fingerprint data recognized in the system. After 5 seconds, the solenoid doorlock will close again automatically.
Additional Analysis and Explanation
The design of the door lock prototype is very relevant to the need for a better security system in the modern era. The existence of fingerprint technology has been proven to be one of the safest methods of identifying, considering that each individual has a unique fingerprint. This makes it almost impossible to be falsified compared to traditional key methods.
The keypad system included in this design also provides additional benefits. In situations where the fingerprint sensor may not be able to function optimally, for example when the condition of the hands is wet or dirty, the keypad becomes a reliable alternative. The use of these two verification methods not only increases the level of security but also provides comfort for users.
Buzzer as a Warning System
Buzzer as a warning system is also an important feature in this prototype. With the existence of voice notifications, users can immediately realize if there is an unauthorized access effort. This can reduce the risk of theft or other illegal access.
Further Development
In terms of further development, the use of Arduino Uno as a control basis makes it easy for modification and system improvement. Users can add other features such as face recognition or integration with smartphones for long distance control, which can further enhance safety and comfort.
Conclusion
Thus, this door lock prototype is an innovative step in designing a modern and effective security system. The combination of biometric technology and manual input with the presence of a warning system provides a comprehensive solution in maintaining door security.
