Abstract

Nowadays, the security issues considered as significant topic specifically in this high technology social. This project aim is to design and develop a smart door lock based on the use of Internet of Things (IoT), test the functionality of the smart door and analyze the effectiveness of smart door lock in term of security which can ensure security as well as lower the cost of implementation. Weight sensor was employed in sense the occurring of people in front of the door. Keypad and smartphone application are purpose to lock and unlock the door. A camera was employed for user to observe the situation in front of the door when needed. A microcontroller was used to control whole system in this project. The user can unlock the door easily by using smartphone application or keypad and they will receive a notification when the system detects unauthorized access, then user can open the camera and observe the situation in front of the door. Smart door lock performing good in reduce the security issues by giving a reminder to user when sense weirdo in front of the door. As a conclusion, the smart door lock that develop based on IoT can operate normally by using smartphone application and the system will always send notification to users when detects unauthorized access to improve the security problems.
