Rancang Bangun Sistem Keamanan Pintu Rumah Menggunakan Solenoid Door Lock dan Magnetic Switch Sensor dengan Notifikasi dan Kontrol Melalui Telegram

Abstract

Currently, home security systems still rely on conventional locks that are prone to break-ins and do not provide real-time alerts. Conventional locks allow anyone with a duplicate key to access the house, and keys are often lost. To address this issue, a home door security system based on IoT with the ESP8266 microcontroller was developed. This system is equipped with a Solenoid Door Lock and a Magnetic Switch sensor. Integration with Telegram enables notifications when the door is opened and access to lock the door. A 4x4 keypad is provided as an alternative if the internet connection is lost. Testing results show the system functions well: accurate sensor detection, responsive password input, and quick notification reception. This system provides an effective and modern solution for home security.
