The problem RFID Smart Door Lock (IOT Based Project) solves

The security aspect is the highest concern for everyone. To reach an acceptable implementation for the smart door lock security should be taken as a major challenge. So the main problem is that the locks coming in the market are highly priced and easily damageable and not affordable for the middle-class people.

Not visible from outside !!
All the sensors and components of the door are not visible from the outside and are attached to the inner side of the door which makes it resistant to any kind of damage to sensors.
Also, any burglar will think that someone might be there in the house because the house is not locked from outside

Multiple mechanical locks !!
Our door lock will contain 4 mechanical locks on the door making it very difficult to break the door and enhance its security.

Alert Features !!
When the burglar will try to break the lock then the light of the lobby will turn on making the burglar think that someone is there in the house.
If the burglar continues his activity in trying to break the lock then the alert siren will turn on and alert the owners and neighbors.

Controlled by mobile application !!
This digital lock can also be unlocked with the help of a mobile phone application.

Challenges we ran into

Connecting of proper microphone sensor in proper way and testing it and fixing its bugs.
