Motel Room Monitoring System

IoT system that connects Arduino sensors to track room occupancy in real-time across an entire motel. Staff monitor availability from a central desktop app, and managers check live status from anywhere via the web dashboard. The system also generates automated occupancy reports, revenue analytics, and check-in/check-out history.
