Numerous control systems for home security purposes have been designed over the years to prevent access to the unauthorized user. The main aim of the control systems is for providing a security for our lives and property for home, schools, offices etc. Therefore, it is important to have a smart technology of achieving this goal. Automatic door system has become a standard feature on many different types of buildings and homes. Further, they are becoming popular due to an effective electronic device which provides high security. Home security has been a major issue because of the increase in crime rate and everybody wants to take proper action to prevent unauthorized users. There was a necessity to automate home so that user can take advantage of the IoT technology as well. Therefore, this project is to develop a prototype of a door security code system using smart device Bluetooth as a key and interface with the IoT in order to monitoring the system. This project was successful working and thus, this design can be a good candidate for home security applications
