Smart Door Lock Raspberry Pi

Making a digital door lock smart with a raspberry pi by christian cawley news 7th august 2018 while a standard lock can be made smart by adding a servo several systems can be purchased that help you do this digital keypad locks can also be enhanced.

Smart door lock raspberry pi.

Because of this we will need to use an external power source and relay to operate the lock. You can also add intelligent lighting a controllable door lock and facial recognition all powered with your raspberry pi. 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.

Prepare dual voltage 5v 12v power supply to power raspberry pi and electronic door strike simultaneously. 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. The gpio pins of the raspberry pi can give an output of 3 3v but the solenoid lock requires 7 12v to operate. 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 create an internet connected smart door lock using your raspberry pi 3 single board computer. 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. 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.

So let s ignore super expensive door systems and build our own. Connect the vcc and gnd of the relay module to 5v and gnd of raspberry pi.
