smart lock is an electromechanical lock which is designed to perform locking and unlocking operations on a door when it receives such instructions from an authorized device using a wireless protocol and a cryptographic key. to execute the authorization process. It also monitors access and sends alerts for the different events it monitors and some other critical events related to the status of the device. Smart locks can be considered part of a smart home.

Most smart locks are installed on mechanical locks (simple types of locks, including deadbolts) and they physically upgrade the ordinary lock. Recently, smart locking controllers have also appeared at the market.

Smart locks, like the traditional locks, need two main parts to work: the lock and the key. In the case of these electronic locks, the key is not a physical key but a smartphone or a special key fob configured explicitly for this purpose which wirelessly performs the authentication needed to automatically unlock the door.

So I made this smart Door Lock which can be connected through Bluetooth and Wi-Fi also, and I insert a special chip for monitoring high power current and safe from other security, and it's Bluetooth connection or Wi-Fi connection is fully secured, and it can connect and give command through Alexa and Google Assistant or Google Home Mini. For coding and BOM (Bill of materials) please follow me in PCB way and get interesting project.
