The Sound Event Detection Module is a high-performance edge-audio recognition board designed for instant, local sound classification. It reliably identifies five critical sound events—baby cry, glass break, gunshot, T3/T4 smoke/CO alarms, and snoring—entirely offline to ensure maximum data privacy. When paired with a Seeed Studio XIAO controller, it integrates seamlessly with ESPHome and Home Assistant, making it the perfect choice for privacy-centric smart home automation and security. Features AI-Powered Edge Computing: Utilizes the AIZIP sound event model, running 100% locally for zero-cloud dependency, ultra-low latency (≤500ms), and absolute privacy. High-Precision Acoustic Recognition: Supports 5 distinct sound categories with a recognition accuracy of ≥95%, ensuring reliable triggers for safety applications. XIAO Ecosystem & Arduino Ready: Specifically designed for the Seeed Studio XIAO series to enable wireless communication. It is fully compatible with the Arduino IDE for rapid development. Native Home Assistant Integration: Plug-and-play support for ESPHome when used with XIAO, enabling automated smart home actions like lighting alerts and mobile push notifications. Versatile Dual-Interface Design: Equipped with both UART and USB interfaces, allowing for real-time monitoring and effortless firmware updates. Customizable Configuration: Easily adjust modes, select specific event triggers (1-5 types), and calibrate sensitivity thresholds via hardware switches or AT commands.
