Bird Call Identifier Kit with ESP32 + LED
Bird Call Identifier Kit with ESP32: Build an Edge ML Bird Sound Classifier
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 hiking through the Western Ghats, hearing a bird call you’ve never encountered. With this kit, you'll build a portable device that listens, records a 3-second clip, and identifies the species instantly — all without an internet connection. Designed for wildlife researchers and citizen scientists, the Bird Call Identifier uses an ESP32 to run a machine learning model right on the edge, classifying birds by their spectral features.
What You'll Build
You’ll construct a battery-operable audio classifier in a compact enclosure. Point it at a bird, capture 3 seconds of audio with a press, and watch the OLED display reveal the species name while the LED ring lights up in species-specific colors. The device logs every identification to a MicroSD card for later analysis, making it a valuable tool for field surveys and biodiversity monitoring.
What You'll Learn
- Capture high-quality audio with the I2S MEMS microphone and ESP32
- Extract spectral features (MFCCs) from audio signals for machine learning
- Deploy a pre-trained TensorFlow Lite model on the ESP32 for on-device inference
- Display results on an OLED and control an addressable LED ring for visual feedback

Who This Kit Is For
This kit is built for wildlife researchers and serious birders who need a reliable, field-ready identifier. It’s especially suited for B.Tech ECE students taking up biodiversity-focused Smart India Hackathon projects, M.Sc. ecology researchers deploying acoustic monitoring stations, and citizen scientists contributing to platforms like eBird India. If you’re comfortable soldering and want to understand edge ML from the ground up, this kit is for you.
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 AI companion (QR on box) provides step-by-step assistance, and our WhatsApp support responds within hours for any roadblocks.
Can I add more bird species to the model?
Yes, the kit includes a pre-trained model for 20 common Indian species. Using provided Python scripts, you can record additional samples and retrain the model on your computer, then deploy the updated model via USB.
Does this require an internet connection in the field?
No. All audio capture and classification happens on the ESP32. The model runs locally, so you can use the device deep inside forests without any network.
Is soldering experience required?
Yes, this is an advanced kit. You'll solder the microphone, OLED, LED ring, and other components onto the prototype board. The included soldering iron and wire make it a complete package, but you should be comfortable with basic soldering techniques.
Wildlife Research — ESP32 samples 3-second audio clips. Edge ML model classifies genre from spectral features without cloud.
