08:55 AM IoT Music Recommender Bug #4508 (Resolved): GSR Sensor Signal Noise Interference
- Commit: r102 - Added 10-point moving average filter to sensor_input.cpp. Accuracy improved by 15%.
-
- The skin conductance (GSR) readings are showing erratic spikes when the ESP32 WiFi module is transmitting data. Resolution needed: Implement a 10-point moving average software filter or add a decoupling capacitor to the sensor power line.
-
- Commit: r105 - Implemented PKCE flow for OAuth2 authentication; verified secure token exchange and refresh logic. Resolved 401 Unauthorized error during playlist trigger tests.
-
-
- Setup the secure login flow using Spotify's Developer API. The system must be able to request "user-modify-playback-state" permissions to trigger the recommended playlists automatically based on the detected emotion.
-
- Create a web-based dashboard using Flask/React to visualize the incoming bio-signals and the resulting emotion classification. This will serve as the primary interface for User Acceptance Testing (UAT).
-
- Develop a Python/C++ script to extract Heart Rate Variability (HRV) from raw pulse sensor peaks. This feature is critical for the ML model to distinguish between "High Stress" and "Active Excitement."
