Sound Event Detection Module D1
A compact edge audio board delivers real-time sound event detection with strong privacy protection. It detects five abnormal sound events — Baby Cry, Glass Break, Gunshot, T3/T4 Alarms, and Snore, enabling immediate response and reliable early warning. Seamless compatibility with XIAO, easy integration for native ESPHome and Home Assistant, ideal for home security monitoring or responsive automation triggers.
-
Ultra-Fast Sound Event DetectionReal-time detection (≤100 ms) ensures immediate awareness and faster reactions, enabling timely alerts and enhanced protection without delay.
-
AI-Powered Edge Processing with High-Accuracy DetectionDelivers precise on-device analysis with a detection rate of >95% and a false positive rate of <2%. This ensures highly reliable identification of five distinct sound events (Baby Cry, Glass Break, Gunshot, T3/T4 Alarms, and Snore).
-
Fully Local Processing with Privacy ProtectionAll sound analysis is performed entirely on-device, with no audio recording or data storage involved. Transmits only detection results and timestamps for alerts—never raw audio data. Ensures strong privacy protection and secure deployment in sensitive environments.
-
XIAO Ecosystem CompatibilityDesigned for the Seeed Studio XIAO series to enable remote wireless communication. Fully compatible with the Arduino ecosystem for seamless integration.
-
Smart Home Integration & Customizable ConfigurationNative ESPHome integration with seamless compatibility for Home Assistant with XIAO series, allowing for automated actions such as lighting triggers and push notifications.
-
Developer-Friendly Design with Flexible ControlFeatures both UART and USB interfaces for real-time monitoring and easy firmware updates. It also supports flexible configuration via hardware switches or AT commands, enabling mode selection, event customization (1–5 types), and precise sensitivity tuning to adapt to different application needs.
Application
Smart Home Automation:
Detect abnormal sound events such as baby crying, glass breaking, or snoring to automatically trigger smart home actions. With fully local processing and no audio recording, it ensures privacy-focused monitoring for everyday environments. Seamless integration with Home Assistant enables users to easily customize detection types and sensitivity based on real-world needs.
Security & Intrusion Detection:
In residential, office, or remote environments with periods of unattended operation, this sound event detection audio board provides low-power, long-duration, and precise sound monitoring. It complements traditional vision-based security systems by covering blind spots where cameras may be limited, delivering more comprehensive and reliable protection.
Office & Workspace Safety:
Deploy in offices or shared spaces to detect emergency alarm sounds (T3/T4) and trigger automated workflows or alert systems.
Edge AI Prototyping & Integration:
Integrate with microcontrollers and automation platforms (e.g., ESPHome, Home Assistant) for custom IoT solutions requiring lightweight, on-device sound intelligence.
