Triple Security System Menggunakan Sensor Fingerprint, Sensor RFID dan Keypad Berbasis Arduino Uno

Abstract

Security is one of the important aspects in minimizing crime, therefore security is very important in human life at this time. When there is no security in an environment, the potential for crime will increase, so at this time people are competing to improve the quality of security by presenting security guards and sophisticated technological tools. I developed a security tool by presenting three security systems in one technology, the working principle of this tool is to confirm the identity of the owner using three layers of security namely Fingerprint sensor, RFID sensor and keypad. When the Fingerprint is read, the system will ask for confirmation from the RFID sensor, when the RFID has been confirmed, it will switch to asking for confirmation to the keypad in the form of the password coded input that has been created, when the Fingerprint, RFID and keypad password input are confirmed the door lock will be active and the door will open. If one of them is not confirmed the doorlock will not activate so the doorlock will not be opened. This tool also has an LCD to display the current state of the tool. With these three layers of security, of course, it can improve the quality of security in an environment so that it helps reduce crime in an environment.
