Build a Smart Baby Monitor with ESP32-S3 & Edge Impulse Sound Classification

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

Inspired by the precision of wildlife research where edge AI identifies specific animal calls, this kit brings the same technology into your home. You will build a compact device that sits in the nursery, listens through a high-sensitivity I2S microphone, and runs a custom-trained neural network on the ESP32-S3 to distinguish your baby's cry from background noise. The moment a cry is detected, the unit triggers a loud buzzer, flashes two red LEDs, and wirelessly alerts a separate parent receiver - so you never miss a moment that matters.

What You'll Build

You will assemble two functional modules: a sound-sensing transmitter that captures audio and classifies it in real time, and a battery-operable receiver that buzzes and lights up the instant a baby cry is recognized. The transmitter streams high-quality audio over I2S, runs the pre-trained Edge Impulse model directly on the ESP32-S3, and sends an alert packet via the NRF24L01 radio link. The entire project fits on a breadboard, with clear wiring and no soldering required.

What You'll Learn

• Deploy a machine learning model on an ESP32-S3 using Edge Impulse
• Interface an INMP441 I2S MEMS microphone for high-fidelity audio capture
• Process real-time sound data and perform on-device inference
• Build a wireless alert system using NRF24L01 modules
