Door Lock with Facial Recognition

Project Description

The door is designed to open when the owner's face and one-time password is verified. When the ultrasound sensor detects a person is approaching, the camera turns on. If the owner's face is recognized, a password is generated and sent to the owner's gmail in QR code to scan. The camera does the verfication real-time. The servo turns, and the door opens for the owner to enter

• Make connections to pins on raspberry pi
  • Motor: 7
  • LED 1: 13
  • LED 2: 15
  • PIR Sensor: 37
• Make connections to pins on arduino
  • Trigger: 7
  • Echo: 6

python3 lock.py

How to use generator.py script

The generator.py generates one time password. A qrcode is produced.

• Create a python script and ensure generator.py is on the same directory level
• Copy the following snippet to the python script to run

from generator import *
token = mkpassword()
print(token)
create_qr_code(token)

How to use the password.py script

The password.py script sends the client.png and password.png to gmail. Email: islacchi.giftia@gmail.com Password: ubuntu123! (Expires on 20 Jan, 2019)

• Create a python script and ensure password.py is on the same directory level
• Copy the following snippet to the python script to run

from password import *
print("sending email")
owner = "Isla"
send_password = Password(owner)
send_password.run()
print("email sent")

How to use the scanner.py script

The scanner.py checks whether the password tallys before opening the door

• Create a python script and ensure scanner.py is on the same directory level
• Copy the following snippet to the python script to run

from scannner import *
password = "1234567890"
qrscanner = QRScanner(password)
open_door = qrscanner.run()
if open_door:
    print("open door")
else:
    print("close door")

How to use the internet.py script

The internet.py checks the internet connection before opening the door

• Create a python script and ensure internet.py is on the same directory level
• Copy the following snippet to the python script to run

from internet import *
response = test_internet_connectivity()
if response == 0:
    print(hostname + " is up")
else:
    print(hostname + " is down")

How to use the camera.py script

The camera.py starts up the camera for 5 seconds and check if the face belongs to one of the owners. A client.png image is produced.

• Store all the owner faces in the images directory
• Go to camera.py and update the dictionary constants_name to map the name of owner to image
• Create a python script and ensure camera.py is on the same directory level
• Copy the following snippet to the python script and run

from camera import *
get_owner_image_encoding()                  
camera = Camera()                          
open_door_data = camera.run()              
if open_door_data[1]:
    print("door is opening")
    print("Welcome " + open_door_data[0])
else:
    print("door will not open")
