PPE Compliance Helmet Detector Kit with ESP32 + Camera
ESP32 Helmet Detector Kit: Build an AI-Powered PPE Compliance System for Factory Entry
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Using an ESP32-S3 and OV2640 camera, this kit places you at the heart of factory floor automation. You’ll deploy an ESP-DL person detection model that verifies hard hat presence at a simulated entry gate. When a worker without a helmet is spotted, the system triggers a relay to deny access or sound an alarm—replicating the intelligent checkpoints now mandatory in India’s manufacturing corridors.
What You'll Build
You’ll assemble a complete PPE compliance checkpoint that uses computer vision to detect workers and check for helmets. The system captures images, runs an AI model, and activates a relay and buzzer if safety gear is missing—just like the systems used in manufacturing plants across India. Bring the rig to life on a prototyping board and mount it at a mock gate for live demos.
What You'll Learn
- Deploy a pre-trained ESP-DL model for person detection and helmet verification
- Integrate OV2640 camera module for real-time image capture on a microcontroller
- Wire a 5V relay and active buzzer for immediate physical output control
- Optimize edge AI inference for fast, offline decision-making in safety-critical environments

Who This Kit Is For
Ideal for CBSE Class 11-12 students exploring AI applications, B.Tech ECE/EEE undergraduates working on industrial IoT projects, and participants in Smart India Hackathon tackling safety automation challenges. ATL Tinkering Labs will find it a perfect fit for teaching embedded vision with direct factory-floor relevance.
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 for the AI companion that walks you through each connection and code block. If needed, WhatsApp our support team for real-time help.
Does the AI model work with different helmet colors or types?
The model detects persons and a hard hat shape; it works with standard industrial helmets across colors. You can fine-tune with additional images for niche helmet designs.
Can this system be used outdoors at a real gate?
It’s designed as a learning prototype. For outdoor deployment, you’ll need a weatherproof housing, lighting control, and maybe a more robust camera module, but the core inference logic remains the same.
Is any cloud connection required?
No, all AI inference runs directly on the ESP32-S3 using ESP-DL. The system functions completely offline, just like edge devices on a real factory floor.
OV2640 + ESP-DL person detection model checks for hard hat presence at factory entry gate. Triggers relay.
