ESP32 Industrial Face Recognition Lock Kit with Camera - Compoden
Build an Industrial-Grade Face Recognition Access Control System with ESP32-S3 and OV2640 Camera
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 any entry point into a biometric-secure access terminal. This kit combines the ESP32-S3's neural processing capabilities with an OV2640 camera to run face detection and recognition entirely on-device. Enroll up to five authorized faces; the solenoid lock releases only on a positive match. Every access event is timestamped via DS3231 real-time clock and logged to a microSD card, creating a tamper-proof audit trail for labs, server rooms, or industrial workstations.
What You'll Build
You will assemble a self-contained unit that captures high-resolution images, runs ESP-DL inference to identify faces, and actuates a 5V solenoid lock instantly upon verified recognition. A 0.96-inch OLED displays system status, match confidence, and door position. The entire circuit fits inside the supplied enclosure and mounts on a door frame, powered by a single 5V adapter. The edge-based design means no cloud dependency - enrollment and recognition happen locally, ensuring privacy and sub-second response.
What You'll Learn
- Train and deploy ESP-DL face recognition models on ESP32-S3's vector extensions
- Interface the OV2640 camera module and capture frames for AI inference
- Drive a solenoid lock through a relay with 1N4007 flyback protection diode
- Log events with RTC timestamps to microSD and display real-time status on OLED

Who This Kit Is For
Engineering students building a final-year major project in face recognition will find the ESP-IDF and ESP-DL workflow directly applicable. Smart India Hackathon teams working on biometric security and industrial automation can prototype a fully functional demo within a weekend. ATL tinkering labs, B.Tech ECE/EEE departments, and diploma programs across NIT, VIT, BITS, and state universities can use this to teach edge AI and embedded systems integration.
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 inside the box to launch the AI companion trained on this project. It covers wiring, code debugging, and calibration. If needed, you can directly message our support team on WhatsApp for personal guidance.
Can I enroll more than five faces or change the recognition algorithm?
Yes, the ESP32-S3 has enough flash and PSRAM to expand the database. Our AI companion explains how to modify the ESP-DL model and adjust storage parameters for up to ten faces, with the same sub-second inference.
Is this kit suitable for a B.Tech major project in a university like VIT or NIT?
Absolutely. The kit meets industry-relevant outcomes - edge AI, sensor integration, and actuator control - that align with final-year ECE/EEE curriculum requirements. The companion material includes a project report template and viva-readiness guide tailored for Indian university panels.
Can I integrate this lock with an existing Wi-Fi network for remote monitoring?
Yes, the ESP32-S3 has built-in Wi-Fi. The AI companion walks you through additional code to push access logs to a web dashboard or send Telegram notifications on unauthorized attempts, all using the same hardware.
Industrial Automation - OV2640 + ESP-DL face detection enrolls and recognises 5 faces. Solenoid lock controlled on match. Log to SD.
