Bird Call Identifier Advanced Kit with ESP32 + Relay
ESP32-S3 Bird Call Identifier Kit with Instant Relay Shutoff 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 enables you to build a field-ready device that listens continuously for a specific bird call around heavy machinery. When the ESP32-S3’s WakeNet neural network identifies the target sound, the system triggers a relay within 100 milliseconds—fast enough to halt a conveyor or turbine—and logs the incident to an SD card with an RTC timestamp. Designed for hands-on wildlife research, it’s your complete hardware and software stack for deploying an acoustic safety net where birds and machines intersect.
What You'll Build
You’ll assemble a weather-resistant DIN-rail enclosure holding a dual-microphone audio front end, edge AI inference on an ESP32-S3, and a dual-relay output stage. The unit mounts near machinery, listens through I2S MEMS mics, and if the pre-trained bird call or distress keyword is detected, it instantly cuts power through the relay. At the same moment, it writes a timestamped event record onto the SD card and shows the status on the 0.96-inch OLED. Everything from soldering the proto board to configuring WakeNet and testing latency is covered step by step.
What You'll Learn
- Training and deploying WakeNet keyword-spotting models on the ESP32-S3 for custom bioacoustic sounds
- Streaming dual I2S microphone data and performing real‑time inference without buffering lags
- Triggering a solid-state relay with deterministic sub‑100ms response using interrupt-driven logic
- Power regulation from a 12V industrial PSU to clean 3.3V/5V rails and flyback diode protection for inductive loads

Who This Kit Is For
B.Tech ECE and EEE students building final-year projects in embedded AI or wildlife tech; Smart India Hackathon teams tackling environmental sensing challenges; ATL mentors guiding advanced tinkering on edge computing; IIT/NIT/VIT/BITS researchers prototyping low-latency acoustic monitoring. If you need a working reference design that goes from microphone to machine shutoff without cloud dependency, this kit matches that brief.
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 inside the box to start a chat with the AI companion, which has step‑by‑step images and code for every module. If you hit a snag, send a WhatsApp message and our team will jump in.
How accurate is the bird call detection, and can I train it for a different species?
The kit includes a pre‑trained WakeNet model for a common stop keyword, but you’ll learn to capture your own samples and retrain the network using Espressif’s tools. Accuracy depends on audio quality and environment, typically exceeding 90% in field tests with proper enclosure and mic placement.
What types of machinery can the relay control?
The dual 5V relay modules can switch loads up to 10A at 250VAC or 30VDC with the included 1N4007 flyback diodes. You can directly cut power to a small motor, conveyor, or turbine controller, or use the relay output as a signal to a larger contactor.
Is soldering experience required?
Yes — you’ll solder the proto boards, connectors, and passive components. The included soldering iron and wire make it a complete workshop-in‑a‑kit. A steady hand and basic soldering skills are expected, and the AI companion shows joint‑by‑joint photos of every connection.
Wildlife Research — WakeNet listens for stop keyword near dangerous machinery. Triggers emergency relay within 100ms, logs to SD.
