ESP32-S3 Audio Classifier Kit: Detect Glass Break, Alarm, Baby Cry

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

Turn a tiny ESP32-S3 board into an intelligent sound alert system that tells glass break apart from a security alarm or a baby's cry - no cloud connection needed once trained. Using Edge Impulse's cloud ML workspace, you'll capture sound events with the high-quality INMP441 microphone, train a neural network, and deploy it directly to the board. Every detection triggers an MQTT alert you can route to a phone notification, home automation, or logging dashboard.

What You'll Build

You'll have a compact, always-on sound sensor that publishes real-time events over Wi-Fi. Place it near a workshop window to catch break-ins, next to a smoke alarm to log auditory warnings, or in a nursery to monitor baby cries. The board's built-in Wi-Fi connects to any MQTT broker, letting you chain actions like turning on lights, sending SMS, or storing logs for later analysis.

What You'll Learn

• Capturing high-fidelity audio with an INMP441 I2S mic and ESP32-S3
• Pre-processing audio into MFCC spectrograms for Edge Impulse
• Training a neural network to classify glass break, alarm, and baby cry sounds in Edge Impulse cloud
• Exporting the model to the ESP32-S3 and publishing events over MQTT
