Noise Pollution Logger Kit v2 — Build a Fully Offline Voice-Controlled Robot with ESP32-S3 and Edge Impulse

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

Assemble a robot that responds to your spoken commands — forward, back, left, right, stop — without ever touching an internet connection. The same hardware doubles as a noise pollution logger when you swap to a sound classification model trained in Edge Impulse. From robotics hobbyist to CBSE engineering graphics student, this kit puts real embedded AI into your hands.

What You'll Build

You'll construct a 2WD robot chassis, wire the ESP32-S3 to the I2S microphone and motor driver, then flash a pre-trained Edge Impulse speech recognition model that runs entirely on-device. Once it rolls, train a second model on environmental sound samples — clapping, traffic hum, drilling — and use it to log noise levels across your school or neighborhood, storing data on an SD card or transmitting via WiFi.

What You'll Learn

• Edge Impulse model creation and deployment on ESP32-S3 for offline speech recognition
• I2S MEMS microphone integration and audio feature extraction
• Driving DC motors through L298N with PWM speed control
• Building a real-world environmental monitoring system using sound classification

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

CBSE Class 11 and 12 students pursuing skill subjects like Applied Mathematics or Artificial Intelligence will find this a ready-made project for internal assessments. B.Tech ECE and EEE freshers can use it for micro-project submissions and Smart India Hackathon demos. ATL Tinkering Lab mentors appreciate the blend of mechanical assembly and edge AI that keeps teenagers 15–18 engaged beyond textbook theory.

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.
