License Plate Recognition Gate Controller Kit with ESP32 + Camera
License Plate Recognition Gate Controller Kit with ESP32-S3 & OV2640 Camera — On‑Device AI Automated Barrier System
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 an ESP32-S3 into an intelligent gatekeeper that reads vehicle number plates in real time, segments characters entirely on‑device, and triggers a heavy‑duty barrier servo — no cloud, no subscription. This kit is engineered for makers ready to deploy a working edge‑AI solution for automated access at gated communities, private parking lots, or as a rigorous final‑year engineering project.
What You'll Build
A self‑contained embedded system that captures a vehicle's license plate image using the OV2640 camera, isolates each character via segmentation, classifies them with a custom convolutional neural network running on the ESP32‑S3, logs the entry with a DS3231 timestamp on a microSD card, and actuates an MG996R servo to open a physical barrier — all in one seamless, low‑latency pipeline.
What You'll Learn
- Deploying a digit/character CNN on ESP32‑S3 with TensorFlow Lite Micro
- Interfacing OV2640 camera, TFT display, and servo on a single embedded platform
- Real‑time image preprocessing and segmentation in C/C++ on constrained hardware
- Designing a robust power system with buck converter for 12V servo and ESP32 logic

Who This Kit Is For
This kit is designed for final‑year B.Tech (ECE/EEE/CSE) students building capstone projects, Smart India Hackathon teams tackling IoT and AI challenges, and embedded systems researchers at IITs, NITs, VIT, and BITS Pilani. It is equally suited for industry professionals prototyping automated parking solutions or a DIY gate controller for a residential society.
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?
The dedicated AI companion walks you through each step; for additional support, you can also reach out on WhatsApp for direct guidance from our team.
Does this kit work outdoors for live traffic?
The OV2640 performs reliably in daylight; for low‑light or night use, you can add an IR illuminator. The enclosure protects the electronics from dust and light rain, making it suitable for covered outdoor installations.
Is the character recognition model pre‑trained?
The AI companion guides you through training a custom CNN on Indian license plate fonts using a provided dataset, so you master the full ML pipeline. A pre‑trained model for common plate styles is also available on the Compoden resource portal if you prefer a head start.
Can the included servo operate a real barrier gate?
The MG996R servo can directly drive a lightweight gate arm up to ~10 kg·cm, ideal for a miniature demo or a model. For a full‑sized vehicle barrier, you would interface the servo control signal with a relay driver; the kit teaches the core control logic that translates recognition to actuation.
OV2640 captures vehicle plate. On-device character segmentation + digit CNN on ESP32-S3 controls barrier servo.
