Smart Door Lock Servo Kit with ESP32 + Camera
ESP32-S3 License Plate Recognition Door Lock Kit with Camera and Servo
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Build an automated barrier gate that reads vehicle license plates using a neural network running directly on the ESP32-S3. The OV2640 captures the plate image, character segmentation isolates each digit, and a TensorFlow Lite Micro CNN recognises the number — all without cloud or internet. Perfect for gated communities, parking lot automation, or Smart India Hackathon challenges where edge intelligence matters.
What You'll Build
You'll assemble a full smart lock system enclosed in a tidy box, with a camera on the gatepost, a TFT display showing the recognised plate and access log, an RTC for timestamped entries, a buzzer for alerts, and an MG996R servo that physically moves the barrier arm. Every plate read is logged to the MicroSD card. The system runs offline, so it’s reliable even when network drops.
What You'll Learn
- Deploying a digit-recognition CNN on the ESP32-S3 using TensorFlow Lite Micro
- Capturing and pre-processing images from the OV2640 camera for character segmentation
- Driving a high-torque MG996R servo with precise PWM control for barrier actuation
- Integrating a real-time clock, SD card logging, and TFT display into an embedded system

Who This Kit Is For
Ideal for B.Tech final-year students in ECE/EEE working on IoT-based vehicle access systems, participants of Smart India Hackathon tackling smart city themes, and professionals automating gated communities. If you’re at IIT, NIT, VIT, or BITS, this kit aligns with capstone projects requiring edge AI deployment. It’s also a natural fit for ATL tinkering labs introducing advanced microcontrollers and on-device neural networks.
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 box to start a chat with the AI build companion trained on this kit, or reach us on WhatsApp. We’ll guide you step by step.
Does this system require an internet connection to recognise plates?
No, the CNN runs entirely on the ESP32-S3, so plate recognition works offline. You only need a connection if you want to send logs remotely.
Can I use this kit for a gated community with multiple vehicles?
Yes, you can train the CNN on multiple plate patterns. The kit includes an SD card for storing authorised plates, and you can expand the dataset.
What tools do I need besides the kit?
Everything is included: soldering iron, solder wire, PCB boards, and a power supply. You just need a laptop to upload code.
Smart Lock — OV2640 captures vehicle plate. On-device character segmentation + digit CNN on ESP32-S3 controls barrier servo.
