Bluetooth-controlled smart home automation with adaptive lighting and security features

Abstract

Smart home technologies play a crucial role in energy efficiency and user comfort. However, commercial systems are often expensive and lack customizable security features. This study presents a cost-effective, hybrid-controlled smart home automation prototype designed with microcontroller (MCU) and Bluetooth communication. The system integrates environmental sensing such as temperature, humidity, light, and motion with a Finite State Machine (FSM) control algorithm. A unique “Black Box” feature has been developed using EEPROM to record critical security events and timestamps. The system is controlled via a custom Android application developed with Mobile Application Interface (MIT App Inventor), allowing for both manual override and autonomous operation. Experimental results show that the adaptive lighting algorithm, which employs an exponential smoothing filter, prevents flickering, and the security recording system successfully logs all unauthorized attempts. The proposed system offers a robust application model for Internet of Things (IoT) and embedded systems.

Bluetooth kontrollü uyarlanabilir aydınlatma ve güvenlik özelliklerine sahip akıllı ev otomasyon sistemi

Abstract

Akıllı ev teknolojileri, enerji verimliliği ve kullanıcı konforunda çok önemli bir rol oynamaktadır. Bununla birlikte, ticari sistemler genellikle yüksek maliyetlidir ve özelleştirilebilir güvenlik özelliklerinden yoksundur. Bu çalışma, mikrodenetleyici ve Bluetooth iletişimi ile tasarlanmış, maliyet etkin, hibrit kontrollü bir akıllı ev otomasyon prototipini sunmaktadır. Sistem, sıcaklık, nem, ışık, hareket gibi çevresel algılamayı Sonlu Durum Makinesi (FSM) kontrol algoritmasıyla entegre eder. Kritik güvenlik olaylarını ve zaman damgalarını kaydetmek için EEPROM kullanılarak benzersiz bir “Kara Kutu” özelliği geliştirilmiştir. Sistem, mobil uygulama arayüzü (MIT App Inventor) ile geliştirilen özel bir Android uygulaması aracılığıyla kontrol edilir ve hem manuel geçersiz kılma hem de otonom çalışma imkânı sağlar. Deneysel sonuçlar, üstel düzeltme filtresi kullanan uyarlanabilir aydınlatma algoritmasının titremeyi önlediğini ve güvenlik kayıt sisteminin tüm yetkisiz girişimleri başarıyla kaydettiğini göstermiştir. Önerilen sistem, Nesnelerin İnterneti (IoT) ve gömülü sistem için sağlam bir uygulama modeli sunmaktadır.
