Smart Door Lock System Using Raspberry Pi

Prepare dual voltage 5v 12v power supply to power raspberry pi and electronic door strike simultaneously.

Smart door lock system using raspberry pi.

Because of this we will need to use an external power source and relay to operate the lock. 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. Connect the vcc and gnd of the relay module to 5v and gnd of raspberry pi. 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.

This system is powered by raspberry pi circuit. In order to implement the smart door model we need a list of materials which is briefly mentioned below. 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. Raspberry pi electronic board is operated on battery power supply wireless internet connectivity by using usb modem it includes camera pir motion sensor and a door.

The team at youtube channel hacker house always deliver when it comes to clear detailed tutorials and their newest project how to make a smartphone connected door lock is no exception. 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. The authors of 9 proposed a face recognition security system using raspberry pi which can be connected to the smart home system. The gpio pins of the raspberry pi can give an output of 3 3v but the solenoid lock requires 7 12v to operate.

Eigenface was used the feature extraction while principal. How about a smart door that knows when someone approaches when the post arrives and can even offer remote viewing of the peephole. You can also add intelligent lighting a controllable door lock and facial recognition all powered with your raspberry pi. So let s ignore super expensive door systems and build our own.

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.
