Bird Call Identifier Plus Kit with ESP32: Steerable Beamforming Microphone Array for Wildlife Research

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

This kit lets you build a focused, steerable microphone array that isolates bird calls from any direction. By applying delay-and-sum beamforming with four synchronized INMP441 I2S microphones on an ESP32, you’ll perform acoustic direction-finding and signal enhancement typically found in research-grade equipment. Whether tracking a distant Malabar whistling thrush or isolating a flock of parakeets in a dense canopy, the Bird Call Identifier Plus Kit transforms your field recording setup into a directional sound telescope.

What You'll Build

After assembling the kit, you’ll have a handheld or tripod-mountable beamforming microphone array that streams high-resolution audio to a connected device. Point it in any direction and hear bird calls with clarity, while background noise fades away. The MCP4728 quad DAC and PAM8403 amplifier drive headphones or a field recorder, making it ready for demanding outdoor sessions.

What You'll Learn

• Designing a delay-and-sum beamformer for an array of four I2S microphones
• Configuring the ESP32 for multi-channel I2S audio input and I2C DAC output
• Implementing steerable beamforming algorithms in C/C++ (Arduino or ESP-IDF)
• Interfacing MEMS microphones with high‑precision power decoupling for low‑noise audio

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is designed for wildlife researchers, bioacoustics students, and serious electronics hobbyists aiming to build a professional‑grade directional microphone. It matches final‑year B.Tech projects in ECE/EEE at IITs, NITs, and VIT, as well as field equipment for NGOs monitoring bird populations. If you’ve outgrown parabolic dish mics and need programmatic control, this is your upgrade.

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.
