Smart-Doors v1.0

Smart door opening via Raspberry Pi using face recognition.

Overview:

This project provides software and hardware installation instructions for smart doors. The software is designed to run on a Raspberry Pi, which is an inexpensive ARM-based computer.

Requirements:

• Raspberry Pi (In my case it is Raspberry Pi B+)
• Micro USB charger (1.5A preferable) for power supply your Raspberry Pi
• Micro SD Card
• Starter Kit V3.0 for Raspberry Pi
• Electro-Magnetic Lock
• Raspberry Pi Camera Night Vision
• Relay 5V 10A/250VAC for lock
• Power supply 12V / 1A for power supply your lock. The end of the cable is not important because it must be cut off anyway.
• Raspberry Pi tape - camera 200cm
• Magnetic sensor to open Door

Hardware Setup:

Step 1:

Documentation of hardware settings in preparation...

Using the breadboard to connect the pins:

1. Green led = 5
2. Red led = 4
3. Yellow led = 26
4. Buzzer = 17
5. pinBtn = 13
6. LockDoor = 6
7. Sensor of opening door = 19
8. LCD Screen:
   1. D7 = 18
   2. RS = 27
   3. E = 22
   4. D6 = 23
   5. D5 = 24
   6. D4 = 25

Software Installation:

1. Install Rasbian onto your Raspberry Pi

2. Activate VNC on Raspberry Pi to operate the device remotely via a computer, not via HDMI [Recommend RealVNC]

3. Activate the camera on Raspberry Pi in raspi-config [More info]

4. Install OpenCv 3 [Tutorial].

   Remember to select Python 3 when configuring your virtual environment

5. I recommends run the command "source" each time you open up a new terminal to ensure your system variables have been set up correctly.
   source ~/.profile

6. Next, let's enter on virtual environment: workon cv

   Remember to always work on this project in a virtual environment, otherwise the program will not work without OpenCv

7. Add camera drivers bcm2835-v4l2 to the last line by opening file sudo nano /etc/modules file

8. Install PIL library pip install pillow

9. Install module to control Raspberry Pi GPIO channels pip install RPi.GPIO

10. Install progress bar library pip install progress

11. Now you can enjoy with that project :)

How to use Smart Doors:

1. Face Management

1. Run file 1_face_management.py. This program allows you to manage a list of users based on which faces are recognized.

2. To perform an action, you must enter the listing number. The menu displays:

   • Add user: You enter the nickname of the user, the number of samples you want to give him, and then take pictures of the face.
   • Add sample for user: This will add the specified number of photos to an existing user.
   • Delete user: This can remove a specific user from your list.
   • Show list of users: This shows id, nicknames and the number of samples for each user
   • Run trainer: Every time you want your changes (adding a user, adding samples or deleting a user) to be taken into account when recognizing faces, you must use a trainer.
   • Quit program

   After each, adding a user or samples or removing a user, the program asks if you want to use a trainer. If you plan to do several activities, I recommend that you leave it at the very end, because with a large number of samples it takes a while.

3. To be able to run FaceRecognizer at all you have to add at least one user and run trainer. I recommend that you add at least 200/300 samples for proper operation.

2. Face Recognizer

1. Run 2_face_recognition.py and enjoy the magic of the smart door
2. The program in the terminal will show a list of available users who can open the door.
3. From now on you can open your door with your face :)

Planned improvements

• Add voice control
• Door control using HomeKit (Especially it's about controlling the application over the phone)
• Controlling the system from outside the home.
