Digital Twin-Based Smart Building Management System

Transforming smart building management into a digital twin technology is operational efficiency and safety enhancement. This paper presents a digital smart building management system comprising an Arduino UNO and a Raspberry Pi 3 Model B designed to successfully achieve communication between sensors and device-related activities. Focused features include gas detection alerts, theft detection based on vibration, air quality monitoring (MQ135), occupancy detection (IR sensors), adaptive lighting control (LDR), and temperature/humidity control via DHT11. Early hazard detection is ensured from fire sensors. Real-time data processing with ThingSpeak integrated it contributed to continuous real-time monitoring. Emergency response would thus use a GSM module. The L293D driver controlled ventilation with both a CPU fan and DC motor. Feedbacks are relayed via real time on an LCD display too. This is a truly reliable, efficient, and safe building management system made possible through integrating digital twin technology with an IoT-based automation mechanism.
