Bird Call Identifier Kit
Bird Call Identifier Advanced Kit with ESP32 + LED
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn your fieldwork into a live spectrogram - this kit gives you a portable audio spectrum analyzer that can help identify bird species by their call signatures in the field. Built around the ESP32-S3's vector instructions, the INMP441 I2S microphone captures sound, the ESP32 crunches a 512-point FFT, and the OLED screen paints the frequency bands 30 times per second. Whether you're cataloguing avian biodiversity or preparing for a Smart India Hackathon project, you'll have a working prototype in under 4 hours.
What You'll Build
You'll assemble a compact, battery-friendly wildlife research tool. The 0.96-inch OLED shows a live 16-band spectral decomposition - each column responds instantly to bird calls, insect chirps, or environmental noises. With the code examples provided, you can later extend the kit to log data, trigger an LED alert for specific frequency footprints, or compare calls against a library.
What You'll Learn
- Stream audio from an I2S MEMS microphone and configure DMA buffers for glitch-free capture.
- Compute a 512-point real FFT on the ESP32-S3 using the esp-dsp library and vector extensions.
- Extract 16 frequency bands and render them as smooth bar chart animations on the OLED.
- Optimize frame rates to reach 30fps with double-buffering and careful memory management.

Who This Kit Is For
This kit is purpose-built for Indian students and researchers: CBSE Class 11-12 learners exploring sound waves and FFT in the physics curriculum; B.Tech ECE/EEE undergraduates tackling digital signal processing; and wildlife enthusiasts participating in citizen-science projects like eBird call identification. It's also an excellent starting point for Smart India Hackathon teams prototyping acoustic monitoring devices for forest departments.
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 to launch the AI companion - it offers step-by-step debugging, circuit checks, and code walkthroughs. If you need human help, our WhatsApp support responds within 4 hours on weekdays.
Can this kit actually identify a specific bird species?
Out of the box, it displays the real-time audio spectrum. To build a classifier, you can log frequency patterns to an SD card (not included) and train a simple model on your laptop. The AI companion will guide you through capturing and labeling calls.
Do I need soldering?
No, all connections use the included breadboard and jumper wires. You can have the circuit running in minutes without any soldering.
Is this suitable for field use without a laptop?
Yes, once programmed via USB, the ESP32-S3 runs standalone. Power it with any USB power bank, and the OLED is bright enough for outdoor viewing.
