How do you make a fingerprint door lock at home?
Circuit Diagram and Explanation
- First of all, connect the fingerprint sensor to the Arduino UNO.
- Then connect the I2C LCD module to the UNO.
- After that, connect the relay module to the Arduino UNO as shown in the circuit diagram below.
- The libraries for fingerprint sensor and I2C LCD are easily available.
How do fingerprint door locks work?
Biometric door locks use personally identifiable information in lieu of a traditional key. They use a thermal or optical scanner to store the fingerprints of anyone authorized to unlock your door. Once the scanner determines that you are an authorized user, it prompts you to input a PIN to unlock the door.
What is a fingerprint door lock?
Fingerprint door locks scan the fingerprint of a person to open the door, rather than using a key. Since fingerprints are unique to each person, this biometric method of entry is both more secure and more efficient than keys, too. For the door lock to work, you first have to enter your fingerprint data.
How do you reset fingerprint lock on Samsung?

- Tap on Continue.
- Tap on Pattern.
- Draw the Pattern.
IS fingerprint door lock safe?
Electronic door locks are safe, but only as much as, if not lesser than, normal, non-electronic, keyed locks. Furthermore, almost all of the locks that use fingerprints, Wi-Fi or Bluetooth tend to cease functioning in the event of a power outage, in which case a person has to use a backup key to unlock their door.
How does a fingerprint sensor work on a door lock?
The next time someone places his/her finger on the sensor, it matches the data obtained through the finger with the pre-saved values. If a match is found, access is granted and the door opens. On the other hand, if its someone else trying to get through, access is not allowed and the door remains locked. Simple, no?
Do you need a key for a fingerprint lock?
This is particularly important when you are using the system to secure the doors at your offices and require a lot of people to be able to go in and out. Fingerprint locks are pretty awesome. Secure, affordable, non-intrusive and almost fail safe, these systems don’t require you to carry a key or remember a password.
What’s the difference between iris scanner and fingerprint lock?
Voice based authentication on the other hand, lets you just speak to open the door without even requiring you to place your finger on it. However, iris scanners are very expensive as compared to fingerprint door lock systems and many people may find the experience of getting their eyes scanned, uncomfortable.
Which is the most accurate fingerprint door lock?
Fingerprint door lock incorporates the proven technology. Fingerprint reader scanning is the most mature and tested type of biometric technology. Recent studies on biometrics have shown that compared to the hand method, fingerprint is more accurate and cost-effective.
