Development of an IoT based keyless smart door lock system / Sufian Mohamad … [et al.]

As reported in many streamline media, the number of criminal cases in Malaysia are increasing, mostly due to the bad economy, lack financial sources in the family or due to a negative social environment. The increasing number shows the importance of having a good home security system. In this modern technological era, security system development is enhancing day by day. Most of the modern security system are built to increase the protection and safety level of office buildings, whereby they are equipped with a high-cost system such as the biometric recognitions. According to the current situation in the country, the idea of innovating a more secured door system came out to help in enhancing the safety within the community level especially home, at an appropriate cost. Thus, our project implements the incorporation of Internet of Things (IoT) with a keyless concept to create a more efficient security system prototype. Our project uses an Arduino Uno as the main controller, RFID device to detect the input from user, GSM Module SIM900A to send/receive SMS for verification purposes and few other sensing devices and components. As demonstrated, our system prototype has been successfully developed, tested, and working according to the requirements. As a conclusion, by installing this IoT based Keyless Smart Door Lock System, the safety of the community is more guaranteed because of the enhanced door security features offered. Hence, the worries towards the safety of the family at home also can be reduced.
