## 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 Goal
|
||
|
|
Interface 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
|
||
|
|
|
||
|
|
```
