The Seeed Sound Event Detection Module recognises five sound events locally — Baby Cry, Glass Break, Gunshot, T3/T4 Alarms and Snore — with no cloud required. Pair it with a XIAO controller for easy ESP Home and Home Assistant smart home automation. The Seeed Sound Event Detection Module is a compact edge audio recognition board designed to identify key sound events locally, without relying on the cloud. It can accurately detect five specific sounds: Baby Cry, Glass Break, Gunshot, T3/T4 Alarms, and Snore, making it a practical option for responsive, privacy-focused monitoring and automation. When paired with a Seeed Studio XIAO series controller, the module can be easily integrated into ESP Home and Home Assistant, allowing you to trigger smart home actions based on recognised sound events while keeping processing local. Features * 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.
