Bird Call Identifier Plus Kit with ESP32 + Relay
ESP32 Bird Call Identifier Plus Kit – Hindi/English Voice Relay 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.
Build a field-ready device that listens for specific bird calls or spoken commands in Hindi and English, then triggers any of four independent relays — perfect for camera traps, automated feeders, or wildlife data loggers. The key innovation: everything runs on the ESP32-S3 without any cloud service, so you can deploy it in the deepest forest with zero internet dependency. Using WakeNet keyword spotting, the kit recognizes words like “cheel,” “maina,” or “record” and instantly activates your connected equipment.
What You'll Build
A portable voice recognition system that detects pre-programmed Hindi and English keywords from ambient bird calls or human commands, displays the word on a 0.96-inch OLED, and toggles any of four relay channels. Use it to trigger a camera trap when a target species vocalizes, activate a water pump at a wildlife pond, or timestamp species presence without human intervention.
What You'll Learn
- Train and deploy WakeNet keyword spotting on an ESP32-S3 entirely offline
- Interface an I2S MEMS microphone for high-fidelity audio capture
- Control a 4-channel relay module with flyback protection for real-world loads
- Display detection results and system status on a 0.96-inch OLED in real time

Who This Kit Is For
Ideal for CBSE Class 11–12 students designing science fair projects on wildlife acoustics, B.Tech ECE students prototyping for Smart India Hackathon challenges, or ATL Tinkering Lab members exploring edge AI. Wildlife researchers who need a low-cost, offline field recorder will also find this kit immediately deployable in sanctuaries and field stations.
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 on the box to launch the AI companion, trained on this exact Bird Call Identifier project. You can also message our support team on WhatsApp for human help.
Can I retrain the kit to recognize different bird calls or regional language words?
Yes. The WakeNet model on the ESP32-S3 can be retrained with your own recordings for any Hindi, English, or other language keywords, and even specific bird vocalizations. The AI companion includes a step-by-step guide for adding custom keywords.
Does the voice detection work without internet or cloud?
Absolutely. All keyword spotting runs locally on the ESP32-S3 using the WakeNet library. No WiFi, no cloud — perfect for remote forest work where connectivity is absent.
Can I use the relays for home automation instead of wildlife equipment?
Definitely. The 4-channel relay module can switch any DC or AC load up to its rating, so you can adapt the kit for voice-controlled lights, fans, or lab experiments once the wildlife project is done.
Wildlife Research — WakeNet detects keywords in Hindi and English to control four relay channels without any cloud service.
