Rancang Bangun Sistem Keamanan Pintun Otomatis Berbasis Arduino Nano Menggunakan RFID-RC522 dengan Interface Android

Abstract

It has been designed to be an automatic door security device using Radio Frequency Identification (RFID) based on arduino uno which of course has a high security system. The design of this automatic door security system does not rely on mechanics as an interface but uses electronic devices in the form of an HC-05 bluetooth module, and Liquid Cristal Display (LCD) to facilitate the supervision of the door security system. In contrast to mechanical locks or manual door security, automatic door security in this security design uses Radio Frequency Identification (RFID) as the opener and servo motor as the driving device, based on the test results carried out, it can be concluded that the simulation of the door safety device can operate properly, in accordance with the design made. In principle, the work of this tool is controlled by Radio Frequency Identification (RFID) sensors and arduino microcontrollers. RFID tags that are registered will be scanned by RFID readers, not everyone can register RFID tags, because there is a keypad where to register RFID tags, so RFID readers have a more guaranteed security system. Then the RFID reader will send data to the arduino nano and activate the relay connected to the Servo Motor, then the door will open. Based on the tests that have been carried out on the tool, this tool has been tested and can be used as an automatic door security using the Radio Frequency Identification (RFID) android interface.
