Sistem Keamanan Kunci Lemari Berbasis Mikrokontroler ESP8266 Menggunakan Suara

Abstract

Modern technology-based security systems have been widely applied in everyday life, one of which is the application of a security system to the cabinet door lock. Voice commands are one of the most popular media for operating home automation systems. In this research, a cabinet locking system with a voice recognition method is made. This security system uses voice to unlock the cabinet door and lock it. By using the ESP8266 Internet of Things microcontroller, this security system can also be controlled remotely. This system uses a solenoid door and a voice password to double the security of the cupboard. This system works when someone wants to open the closet door using a password sent via a smartphone and then processed by a microcontroller. If the password is correct, the door will open. The output result obtained by the detected sound, namely the buzzer, will sound if the cabinet lock is successfully opened or closed. Based on the tests that have been carried out five times, it can be concluded that the ESP8266 microcontroller-based cabinet lock security system using this sound can be used properly.
