Smart Door Lock System Using Raspberry Pi

Here a solenoid lock and a pi camera will be used with raspberry pi to build this face recognition based door lock system using raspberry pi 3.

Smart door lock system using raspberry pi.

In order to implement the smart door model we need a list of materials which is briefly mentioned below. The authors of 9 proposed a face recognition security system using raspberry pi which can be connected to the smart home system. Next up we need to prepare our power supply to provide power both to the raspberry pi which requires 5v and to the door lock which requires 12v and is triggered using the relay switch. You can also add intelligent lighting a controllable door lock and facial recognition all powered with your raspberry pi.

Whenever the person comes in front of the door it recognizes the face and if it is registered then it unlocks the door if the. Because of this we will need to use an external power source and relay to operate the lock. Connect the vcc and gnd of the relay module to 5v and gnd of raspberry pi. Prepare dual voltage 5v 12v power supply to power raspberry pi and electronic door strike simultaneously.

We previously used solenoid lock with raspberry pi and also built few projects with pi camera like web controlled raspberry pi surveillance robot iot based smart wi fi doorbell smart cctv. A lack of drivers for the esp 12e however resulted in noisycarlos switching to a raspberry pi zero w and with the use of some python code the project finally came to life using a mobile app to finally control the lock over tcp with some home protecting encryption added into the mix to prevent anyone hacking the house. Using a raspberry pi powered deadbolt actuator multiple users can remotely unlock a door via a smartphone app. The build can be attached to your existing lock so there s no need to start pulling.

4 1 raspberry pi raspberry pi rp is an arm based single the third generation raspberry pi 3 it has broadcom bcm2837 64bit arm cortex a53 quad core processor soc running at 1 2ghz and 1gb ram. How about a smart door that knows when someone approaches when the post arrives and can even offer remote viewing of the peephole. So let s ignore super expensive door systems and build our own. This system is powered by raspberry pi circuit.

Eigenface was used the feature extraction while principal.
