The Sound Event Detection Module is a compact edge audio recognition board. It accurately detects 5 specific sound events (Baby Cry, Glass Break, Gunshot, T3/T4 Alarms, Snore) locally without cloud dependency. When paired with a XIAO series controller, it can easily integrate into ESPhome and Home Assistant for privacy-focused smart home automation.
- AI-Powered Edge Processing
Powered by the AIZIP sound event model, running entirely locally to ensure data privacy with ultra-low latency (≤500ms).
- High-Precision Recognition
Supports detection of 5 distinct sound events with a recognition rate of ≥95%, delivering precise and reliable performance.
- XIAO Ecosystem Compatibility
Designed for the Seeed Studio XIAO series to enable remote wireless communication. Fully compatible with the Arduino ecosystem for seamless integration.
- Smart Home Integration
Native support for ESPHome & Home Assistant with XIAO series, allowing for automated actions such as lighting triggers and push notifications.
- Dual Interface Design
Features both UART and USB interfaces, facilitating simultaneous real-time monitoring and firmware updates.
- Flexible Configuration
Easily adjustable via hardware switches or AT commands: switch modes, select specific events (1-5 types), and fine-tune sensitivity thresholds.
