Home Smart Light Switch Kit with ESP32 + Camera
ESP32 Home Smart Light Switch Kit – Build an AI Safety Gate with Hard Hat Detection
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform a factory entry point into an automated safety checkpoint. This kit lets you build a camera-based system that actively checks for hard hats—the most common PPE violation in Indian manufacturing floors. When the ESP32-S3 board running ESP-DL's person detection model identifies a worker without head protection, it instantly triggers a relay to cut off machinery access and sounds a buzzer, mimicking real-world industrial gate control.
What You'll Build
A compact prototype that mounts near a doorway. The OV2640 camera captures live images, the microcontroller processes them on-device using an AI model trained to distinguish hard‑hat from no‑hard‑hat, and the output controls a 5V relay. If a worker enters without proper headgear, the relay activates a red LED stack and an active buzzer, while a diode-protected circuit ensures safe switching. Soldering the PCB board yourself gives you hands-on assembly skills that mirror professional product development.
What You'll Learn
- Deploy and fine‑tune a person detection model on ESP32‑S3 using ESP‑DL libraries
- Interface an OV2640 camera and stream frames for real‑time inference without cloud dependency
- Program a relay to control high‑current devices while incorporating flyback diode protection
- Understand how to translate an industrial safety compliance workflow into an embedded AI system

Who This Kit Is For
Designed for Indian students and makers who want to go beyond blinking LEDs. If you're in CBSE Class 12 working on a computer science investigatory project, a B.Tech ECE/EEE student preparing a final‑year demonstration, or competing in Smart India Hackathon with an Industrial IoT theme, this kit delivers a corporate‑ready edge AI solution. ATL Tinkering Labs and clubs at NITs, VIT, or BITS will find the factory‑gate scenario plugs directly into safety‑tech innovation challenges.
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?
You’ll have unlimited access to our AI companion (scanned from the kit box) as well as WhatsApp support from our Bengaluru team. Just send a photo of your board and we’ll help you debug in real time.
My hard hat detection model isn’t triggering the relay consistently. How do I fix it?
Our AI companion will guide you through adjusting the model’s confidence threshold and lighting conditions for the OV2640 sensor. You can also test with your own safety helmet images to fine‑tune the logic.
Can I use this kit for a college minor or major project submission?
Absolutely. The system produces real‑time safety compliance data, and we provide documentation templates to integrate it into your report. Many institutions accept it as an embedded systems or AI project.
Does the kit require soldering, and is that included?
Yes, the soldering iron and solder wire are part of the kit. You’ll solder the relay driver circuit and LED indicators onto the prototype board—a skill that counts heavily in project viva evaluations.
