Industrial Relay Switch Controller Kit with ESP32 + Camera
AI Safety Gate Controller Kit with ESP32 Camera & Relay
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 a factory entry gate that automatically checks if every worker is wearing a hard hat — and locks out access if they aren't. With this kit, you'll train and deploy an ESP-DL person detection model on an ESP32-S3 camera, then wire it to a relay module that controls a warning buzzer and LED indicators. It's a complete Industry 4.0 safety prototype you can build in a single day, bringing AI-powered automation directly to your workbench.
What You'll Build
You'll assemble a standalone unit that captures real-time video from the OV2640 camera, runs on-device AI inference to detect a person and verify hard hat presence, and toggles a 5V relay based on the result. The relay can be wired to a gate lock, alarm, or access control system. This is the core technology behind modern smart factory safety systems — engineered from scratch by you.
What You'll Learn
- Deploy a pre-trained person detection model onto an ESP32-S3 using ESP-DL and the Arduino IDE
- Integrate an OV2640 camera module and capture frames for real-time AI inference
- Control a 5V relay module with transistor-based flyback protection using 1N4007 diodes
- Build a complete industrial control circuit on a prototyping PCB, managing high-current loads safely

Who This Kit Is For
This kit is ideal for B.Tech ECE and EEE students who want a hands-on AI + industrial electronics project. CBSE Class 11–12 students in computer science or vocational electronics streams can use it for practical AI models. It's also a strong entry for Smart India Hackathon participants working on Industry 4.0 safety themes, and a powerful addition to ATL Tinkering Labs or NIT/VIT/BITS Pilani project portfolios.
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 kit box to launch your AI build companion. It can answer wiring, code, and troubleshooting questions specific to this project, and you can always reach us on WhatsApp for human backup.
Can this kit be used for a Smart India Hackathon project?
Absolutely. The hard hat detection and relay-controlled safety gate directly address Industry 4.0 automation and workplace safety problem statements commonly seen in SIH hardware tracks.
Do I need prior experience with ESP32 or AI models?
The kit assumes intermediate comfort with Arduino IDE and basic electronics. You'll load pre-built models rather than training from scratch, but some familiarity with C++ and circuit assembly helps.
How reliable is the hard hat detection in a factory setting?
The ESP-DL model, trained on person and hard hat datasets, performs reliably under typical indoor factory lighting. Testing under your exact conditions is part of the learning experience.
Industrial Automation — OV2640 + ESP-DL person detection model checks for hard hat presence at factory entry gate. Triggers relay.
