Abstract

Security is part of important aspects that needs to be concerned with the community. Especially when it involves lives and properties, many people encounter a problem of a weak security lock system which causing them to feel unsafe. As an example, a burglary problem which is often the case in recent years that may lead to a danger of loss valuable things, raped and murder. Otherwise, home safety lock system that is easy to be cracked by the theft or intruders where it can’t guarantee the safety of a home. Based on the problem, a study is conducted. The purpose of this project is to develop a secret door knocking pattern detector which can recognize the specific knocking pattern and unlock the door if the pattern is correct. As the main controller, Arduino microcontroller is used to control the system of knocking pattern detector that communicates with a piezoelectric sensor. In this system, knocking is used to activate the system and unlock the door through a servo motor by turning the door lock. The system is made up of two main features, the knocking pattern detector and control mechanism. The knocking pattern detector was designed using the piezoelectric sensor to record and detect secret knock pattern. The control mechanism using a servo motor to turn the door lock after receiving a signal from the piezoelectric sensor. Both of the two main features were all controlled by Arduino microcontroller that had a program inside it. As an addition, a push button is added to record a knock pattern as the main step to save the password. This system can be programmable by pressing the programming button and knock again to create a new knocking pattern.
