Smart Door Lock Raspberry Pi

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

Smart door lock raspberry pi.

Because of this we will need to use an external power source and relay to operate the lock. How about a smart door that knows when someone approaches when the post arrives and can even offer remote viewing of the peephole. The circuit diagram for raspberry pi solenoid door lock is very simple as you only need to connect the solenoid door lock to raspberry pi. You can also add intelligent lighting a controllable door lock and facial recognition all powered with your raspberry pi.

You can create an internet connected smart door lock using your raspberry pi 3 single board computer. The gpio pins of the raspberry pi can give an output of 3 3v but the solenoid lock requires 7 12v to operate. Connect the vcc and gnd of the relay module to 5v and gnd of raspberry pi. 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.

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. Raspberry pi smart door lock circuit diagram. Solenoid lock needs 9v 12v to operate and raspberry pi gpio pins can supply only 3 3v so a 12v external power source is used to trigger the lock with the help. It can be unlocked over a wifi connection using a smartphone and a custom app.

So let s ignore super expensive door systems and build our own. In order to implement the smart door model we need a list of materials which is briefly mentioned below.
