While this has been done before i thought i d post my solution.
Raspberry pi unlock door.
Connect the vcc and gnd of the relay module to 5v and gnd of raspberry pi.
This was my first hardware project and instructable ever and i m sure.
Opening and closing the door is secured by using self signed certificates installed on family s mobile phones.
A check with infrared light barriers or other methods would certainly be possible but in this case that is much more complicated.
Due to this a 12v adapter is used to power the solenoid lock.
Circuit diagram for face recognition door lock using raspberry pi is given below.
Raspberry pi and solenoid lock are connected through the relay module.

If the garage door is open when it shouldn t be then send a text message sms to a cell phone.
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.
This instructable explains how i setup a raspberry pi to open my garage door using a smarthphone.
All activity is monitored and logged using the raspberry pi.
On the other side of the relay module connect the negative form dc power source to the negative of the solenoid door lock.
Attach the camera we re going to keep an eye on the outside world by replacing the door s peephole with the raspberry pi camera.
A peep hole is typically a two piece barrel that screws together and can be easily unscrewed from the inside.
Then connect the signal pin of the relay module to the gpio 26 of raspberry pi.
Build a raspberry pi door window sensor with reed relais.
Build the ultimate smart home door lock system turning your office into a high security vault.
You can create an internet connected smart door lock using your raspberry pi 3 single board computer.
The garage door has been in continuous use since late 2014.
It can be unlocked over a wifi connection using a smartphone and a custom app.
In addition to a surveillance camera and motion sensors information about open windows and doors is also of interest to a self built surveillance system.
With a magnet attached to the garage door the pi relies on two magnetic reed switches to check the garage door s status.
Solenoid lock requires 9 to 12v and raspberry pi can provide only 5v.
