Automatic Pet Feeder Kit with ESP32 + Camera
Automatic Pet Feeder with AI Car Plate Recognition — ESP32-S3 Camera 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.
Imagine your pet running to the feeder the moment your car enters the driveway. This project lets you build an intelligent feeding station that reads your vehicle’s license plate using an OV2640 camera and a custom convolutional neural network running entirely on the ESP32-S3. When it spots your car, the barrier relay opens and food is dispensed automatically — no remote, no phone needed.
What You'll Build
A fully functional, autonomous pet feeder that uses real‑time image capture and on‑device AI to recognise your car’s number plate. The system captures a plate image, segments individual characters, classifies them with a CNN, and triggers an MG996R servo to open the food gate only on a match. Feeding times are logged via DS3231 RTC, and every plate image is saved to a microSD card for debugging and training refinement.
What You'll Learn
- Deploying a convolutional neural network on an ESP32‑S3 for real‑time digit classification
- Performing on‑device character segmentation and OCR using the OV2640 camera
- Controlling a high‑torque servo with power management via a buck converter
- Integrating a DS3231 RTC for time‑stamped event logging and scheduling

Who This Kit Is For
This kit is built for B.Tech ECE/EEE students tackling capstone projects, Smart India Hackathon participants, and advanced hobbyists who want a real‑world edge‑AI system. It fits final‑year engineering requirements perfectly and gives IIT, NIT, VIT, and BITS Pilani students a head start on on‑device machine learning with a genuine pet‑care use case.
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?
Open the AI companion through the QR code or reach us on WhatsApp; the assistant was trained on every step of this exact feeder project and can debug wiring, code, and model errors.
Do I need prior machine learning experience?
The AI companion walks you through training the CNN and loading it onto the ESP32-S3, but you should be comfortable with C++ and basic electronics to get the most from this advanced kit.
Can I adapt the plate recognition to detect my pet’s face instead?
Yes — once you master the image capture and segmentation pipeline, you can retrain the CNN with your own labelled pet images; the companion includes notes on dataset preparation.
What if the camera struggles in low light?
The kit includes placement tips and the OV2640 works well in daytime conditions; for night use you can add an infrared illuminator (not included) with guidance from the companion.
Pet Care — OV2640 captures car plate. On-device character segmentation + CNN classifies digits. Barrier relay on match.
