AI Face Detection Entry System Kit with ESP32 + Relay
Secure Your Space with AI: ESP32-CAM Face Detection Entry System Kit
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 intelligent access control system that recognizes faces using an on-device AI model, triggers a solenoid lock, and logs every entry with precise timestamps. Ideal for securing labs, private offices, or maker spaces, this advanced project gives you hands-on experience with edge AI, IoT, and real-time embedded systems. The kit centers on the ESP32-CAM, which runs a lightweight TensorFlow Lite model for face detection, making this a true embedded machine learning application.
What You'll Build
You will assemble a fully functional face-recognition door lock module. The ESP32-CAM captures images, runs detection, and activates a 5V solenoid lock only for recognized faces, while displaying status on the OLED. All unlock events are logged to a microSD card with DS3231 RTC timestamps, providing an auditable access record. The finished unit fits inside the provided enclosure and can be mounted near any door.
What You'll Learn
- Train and deploy a face detection model on ESP32-CAM using TensorFlow Lite Micro
- Interface a solenoid lock with a 5V relay module and manage inrush current safely
- Integrate a DS3231 RTC and microSD module for real-time event logging and OLED display
- Design a stable power circuit with an LM2596 buck converter and decoupling capacitors

Who This Kit Is For
Designed for final-year B.Tech (ECE/EEE) students, hacking club members, and professionals prototyping biometric access control. It fits perfectly into Smart India Hackathon hardware tracks, advanced hobby projects, and research at IIT/NIT/VIT/BITS labs. You should be comfortable with soldering, basic Arduino IDE, and wiring prototype boards—this is not a beginner kit.
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 kit to chat with our AI build companion, instantly aware of your exact project step. If you need human help, a WhatsApp message to our support team gets a reply within hours.
Does the kit include a pre-trained face detection model?
Yes, we provide an optimized TensorFlow Lite model that you flash onto the ESP32-CAM. The companion also guides you through capturing your own face samples and retraining the model for personal recognition.
Can I integrate this with an existing door strike or electromagnetic lock?
Absolutely. The relay module can drive any 5V solenoid or electric strike; we include wiring diagrams for common alternatives. Just ensure your external lock's current rating is within the relay's specs.
What if facial detection fails in low-light conditions?
The ESP32-CAM includes a white LED flash that our code activates automatically in dim conditions. The companion also suggests optional IR illuminators if you need completely covert operation.
ESP32-CAM runs face detection model. Recognised face logs unlock event and triggers solenoid lock.
