Bird Call Identifier Smart Kit with ESP32 + Relay
Bird Call Identifier Smart Kit with ESP32: Offline Wake Word Detection & Relay Trigger for Field 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.
Monitor rare bird species or automate wildlife research tools without relying on an internet connection. Using an ESP32-S3 and WakeNet, this kit trains a custom wake word from recorded bird calls. When the word is detected, a relay instantly activates a connected device like a camera, recorder, or alarm — all offline. Perfect for field biologists, citizen science projects, and CBT/ATL lab experiments.
What You'll Build
You'll assemble a portable, battery-friendly unit that listens continuously for a specific bird vocalization. On detection, a 5V relay switches on so you can trigger a camera shutter, start a data logger, or sound a buzzer. Three onboard LEDs provide visual confirmation of power, listening status, and relay trigger events. The entire pipeline runs locally on the ESP32-S3; no cloud, no Wi-Fi, and no lag.
What You'll Learn
- Capture high-fidelity audio with the INMP441 I2S microphone and ESP32-S3
- Train a custom wake word using Edge Impulse or Espressif’s WakeNet tools, running 100% offline
- Build a relay driver circuit with flyback diode protection for inductive loads
- Program multicolor LED status indicators that respond to detection events in real time

Who This Kit Is For
Built for CBSE Class 11-12 students exploring bioacoustics in their science projects, B.Tech ECE/EEE undergraduates working on embedded AI, and teams participating in Smart India Hackathon wildlife themes. Also ideal for ATL Tinkering Labs where offline, real-world sensing projects are a priority. If you’re studying at an IIT, NIT, VIT, or BITS campus and need a reproducible field-robust monitoring rig, this kit gives you the exact starting point.
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 access the AI companion that guides you through each step, or message us on WhatsApp for human support — we respond within a few hours on working days.
Can I train the kit to detect multiple bird calls?
Yes. You can train WakeNet with several wake words, each corresponding to a different bird species, and program the relay to activate different outputs or record the specific event.
Does the detector need an internet connection?
No internet required. All audio processing and wake word inference run directly on the ESP32-S3, making it ideal for remote field sites.
What kind of device can the relay control?
The 5V relay can switch low‑power loads like a DSLR camera remote, a sound recorder, an LED floodlight, or an external buzzer — everything you need for automated wildlife monitoring.
Wildlife Research — ESP32-S3 WakeNet detects a custom wake word offline. Triggers relay on detection without cloud.
