Biodiversity Sound Recorder – Hear and Identify Every Bird Call with Raspberry Pi

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Straight out of the box, you’ll assemble a compact autonomous recorder that listens to the outdoors every few minutes, capturing crisp audio with the MAX4466 electret microphone. The Raspberry Pi Zero 2W runs a pre-loaded Python script that timestamps each recording and automatically performs spectral analysis — so when a bulbul or sunbird sings, the frequency signature pops up next to the clip, turning your backyard into an instant biodiversity lab.

What You'll Build

You’ll wire the MAX4466 mic to the Pi Zero 2W, load the operating system onto the 16GB MicroSD card, and seal everything inside a waterproof enclosure. Once deployed on a balcony, garden wall, or school campus, the device records short .wav files at set intervals. A spectral analysis algorithm then breaks down the sound into frequency vs. time graphs, comparing peak frequencies with known bird call ranges, so you can log species without ever seeing them.

What You'll Learn

• Wiring a high‑sensitivity analog microphone to a single‑board computer
• Writing (or customising) Python code for scheduled audio capture
• Implementing Fast Fourier Transform (FFT) to extract frequency spectra from real‑world sound
• Packaging electronics for outdoor fieldwork — cable management, waterproofing, and power

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Designed for ATL Tinkering Labs, CBSE Class 9‑12 science projects, and Eco Club initiatives where biodiversity monitoring meets hands‑on electronics. Ideal for students preparing Smart India Hackathon Junior challenges, B.Tech ECE/EEE introductory fieldwork, and VIT/NIT/IIT biodiversity hackathons — anyone who wants to move from a textbook FFT to a box in a tree that actually names the bird.

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.
