# PSB Thinking - March 6, 2026## ESP32 Display Addon Project### Display Teardown Notes- **Microphone array**: At least 2 mics, 5 black wires (likely +power, ground, audio differential pairs)- **Motion sensor**: Sharp-style PIR, 2 glass lenses ~1.5" apart in black housing - 3 wires: likely VCC (5V), GND, signal (High/Low output) - Passive IR detection — triggers High on motion, Low when clear### Project GoalInterface the display's sensors (mics + PIR) with an ESP32 for motion triggering and/or audio detection.### Todo- Wire ESP32 to PIR and mics- Determine exact pinout from Sharp PIR datasheet- Write ESP32 code to read motion + audio signals
