AI Scene Recognition Room Controller Kit with ESP32 + Relay
AI Scene Recognition Room Controller — Build an ESP32 Smart System That Reacts to You
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine walking into your room after a long day, and the lighting dims to a warm glow while the fan slows to a whisper — all because a camera recognized you’re winding down to sleep. This kit makes that a reality. You’ll build a standalone ESP32-CAM device that classifies three room contexts (working, relaxing, sleeping) and triggers real electrical loads through a 4-channel relay module. No cloud dependency, no voice commands; just a device that truly understands the room.
What You'll Build
You’ll assemble a compact, self-contained unit that mounts in a standard enclosure. The ESP32-CAM captures periodic images and runs an on-device activity classifier trained to detect posture and scene cues. Based on the recognized mode, the system automatically switches lighting scenes and a fan — using relays to control AC appliances safely. A DHT22 sensor monitors temperature to adjust fan speed for comfort, and a 0.96‑inch OLED displays real‑time mode and sensor readings.
What You'll Learn
- Train and deploy a lightweight image classifier on ESP32-CAM using edge AI frameworks
- Interface a 4-channel relay module with AC loads and implement flyback protection with diodes
- Integrate environmental sensing (DHT22) to build adaptive automation logic
- Design a custom power supply circuit with a buck converter and noise filtering for stable camera operation

Who This Kit Is For
This kit is designed for B.Tech ECE/EEE students building IoT capstone projects, Smart India Hackathon teams prototyping an intelligent room controller, and professional embedded engineers exploring edge AI. It assumes you’re comfortable reading schematics, soldering, and working with mains electricity. If you’ve built with Arduino before and are ready to take on a serious machine‑learning‑enabled automation project, you’re the right builder.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to access the AI companion that walks you through each step. You can also message us on WhatsApp for direct human support from our team in Bengaluru.
Can I train the esp32-cam to recognise additional activities beyond working, relaxing and sleeping?
Absolutely. The AI companion includes a guide to capture new images and retrain the model. The hardware is fully prepared for custom classes like reading or cooking.
Does this kit require a continuous wifi connection?
No. All inference runs locally on the ESP32-CAM. Wifi is only needed if you later add optional live dashboard streaming; the core classification works offline.
What appliances can I safely switch with the relay module?
The 4‑channel relay can control up to four AC appliances rated under 10A each — ideal for lights, fans, or small heaters. The kit includes 1N4007 diodes for inductive load protection.
ESP32-CAM classifies room activity (working, relaxing, sleeping) and adjusts lighting scene and fan via relays.
