Noise Pollution Logger Kit
Noise Pollution Logger Kit – ESP32-S3 Offline Voice Control for Home Automation
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Control lights and appliances with only your voice — no internet, no cloud, no delays. This kit turns an ESP32-S3 into a privacy-first smart switch that listens for custom keywords like “On”, “Off”, or “Dim”. Whether you’re a student building a CBSE science project or a tinkerer exploring edge AI, you’ll have a complete offline voice IoT system running in hours.
What You'll Build
You’ll assemble a microphone and relay module around the ESP32-S3, then deploy a trained neural network that spots your spoken commands in real time. The finished module can be hidden behind a switchboard to voice-control any lamp, fan, or low-power appliance. Everything runs on the microcontroller — no WiFi or smartphone required.
What You'll Learn
- Capturing high-quality audio with the INMP441 I2S MEMS microphone
- Building a keyword spotting dataset and training a model in Edge Impulse
- Deploying a TensorFlow Lite model on the ESP32-S3 for real‑time inference
- Switching AC loads safely using a relay and interpreting voice decisions as GPIO triggers

Who This Kit Is For
If you’re a CBSE Class 11–12 student exploring microcontroller-based physics projects, this kit delivers an evaluated AI pattern that fits nicely into your curriculum. B.Tech ECE/EEE students can use it for IoT internships or Smart India Hackathon prototypes, and ATL Tinkering Lab mentors will appreciate the ready-to-run voice control module that requires no coding from scratch. Even interested hobbyists who want a plug-and-play offline voice switch will find everything they need inside.
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 in the box to open the AI companion. It knows every step of this project. You can also message us on WhatsApp for human help.
Do I need internet for the voice commands to work?
No. The AI runs entirely on the ESP32-S3. You only need internet during the initial training step on Edge Impulse. After that, voice recognition works offline.
Can I train custom keywords like “Bedroom Light On”?
Absolutely. The included guide shows you how to record your own voice samples on Edge Impulse and train any multi-word command you choose.
Is this kit safe to use with mains-powered appliances?
The relay is rated for up to 250V AC / 10A. Follow the safety instructions in the build guide and never touch exposed terminals when the circuit is live.
Environmental — Edge Impulse keyword model on ESP32-S3 recognises on/off/dim commands and controls a relay — offline voice IoT.
