miniature classroom 3d model

Create a realistic detailed 3D miniature smart classroom prototype for an IoT-based adaptive energy management system. Include a classroom room with walls, windows, door, teacher desk, blackboard, 10–20 student desks and chairs, teacher and student figures. Install 2 ceiling LED lights, 2 ceiling ventilation fans, PIR occupancy sensor, DHT22 temperature/humidity sensor, BH1750 ambient light sensor, ESP32 microcontroller, 4-channel relay module, breadboard, wiring, 20x4 I2C LCD display, and power supply. Add a small electronics/control box mounted on the side. Show all components physically connected with realistic wires. The ESP32 controls the lights and fans based on occupancy, temperature, humidity, and ambient light. Make it a fully assembled working prototype, clean engineering design, realistic materials, accurate component placement, detailed electronics, connected wiring, non-exploded view, no floating parts, no disconnected components, presentation-ready 3D model.
