classroom energy management 3d model

Create a realistic 3D CAD-style prototype of an Adaptive Classroom Energy Management System. Use a transparent acrylic control box containing an ESP32 microcontroller, blue 2-channel relay module, PIR occupancy sensor, DHT22 temperature/humidity sensor, LDR light sensor, and 5V/12V power supply. Include neatly organized red, black, yellow, blue, and green wiring with realistic connectors, terminals, screws, and mounting standoffs. Professional engineering prototype, accurate proportions, hard-surface modeling, photorealistic PBR materials, transparent acrylic, clean wire management, three-quarter isometric view, studio lighting, white background, ultra-detailed 4K render. No sci-fi elements, no messy wiring, no cartoon style, no unnecessary text.
