ESP32-S3 License Plate Recognition Gate Kit with Camera
Motorised Pet Door Kit with ESP32 & Camera - Build a License Plate Recognition Barrier
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This kit lets you construct a motorised barrier gate that captures vehicle number plates using the OV2640 camera, processes character segmentation and digit recognition with a CNN running entirely on the ESP32-S3, and drives a high-torque servo to open or close the gate - no cloud dependency, no recurring fees. It's the perfect AI-at-the-edge project for makers who want to build a real-world access control system.
What You'll Build
A fully functional plate-recognition gate. When a vehicle approaches, the camera takes a shot, the ESP32-S3's on-device CNN extracts and classifies the plate digits, and the MG996R servo lifts the barrier for authorized plates. The TFT display shows status and the active buzzer provides audible confirmation. You'll walk away with a production-ready module you can mount at a parking entrance or driveway.
What You'll Learn
- Deploy a TensorFlow Lite digit-recognition CNN on an ESP32-S3 for sub-second inference
- Capture and pre-process vehicle plate images using the OV2640 camera module under varying light
- Implement character segmentation algorithms and a digit CNN in C for on-device edge AI
- Control a high-torque MG996R servo via PWM to physically operate a barrier gate

Who This Kit Is For
B.Tech ECE/EEE students building final-year projects or competing in Smart India Hackathon, M.Tech researchers prototyping edge AI for vehicle access, ATL Tinkering Lab mentors introducing on-device inference, and professionals from IITs/NITs/VIT/BITS Pilani developing gated-community automation - anyone 25+ who wants hands-on AI without relying on the cloud.
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 to launch the AI companion trained on this exact kit; if you need more help, WhatsApp us directly and an engineer will guide you through the block.
Does this kit require an internet connection for plate recognition?
No. All image processing and CNN inference run on the ESP32-S3. The AI companion is accessible offline once you've loaded it on your phone, and the final gate operates completely standalone.
Can I modify the kit to recognize motorcycle plates or QR codes instead?
Absolutely. The on-device CNN can be retrained for different character sets or symbols. The AI companion includes modification guidance for adapting the segmentation and model to new plate formats or QR scanning.
What soldering skill level is required?
Basic through-hole soldering is needed for the PCB prototype board, buzzer, and connectors. The kit includes a soldering iron and solder wire, and the AI companion provides close-up video walkthroughs for every joint.
