WRAPPER IMPLEMENTATION (C4001_SafeString_Wrapper.h/.cpp):
- Created a comprehensive wrapper class for DFRobot_C4001 sensor
- Provides SafeString support for sensor parameter conversions
- Implemented getters for:
  * getStatusString() - returns formatted sensor status
  * getMotionDetectedString() - returns "Motion" or "No Motion" string
  * getTrigDist(), getMaxDist(), getMinDist() - return int distances in cm
  * getTrigDelay(), getKeepDelay() - return float delays in seconds
  * getTrigSensitivity(), getKeepSensitivity() - return int 0-9

- Implemented setters for:
  * setTrigDist(), setMaxDist(), setMinDist() - take byte* text input
  * setTrigDelay(), setKeepDelay() - convert seconds to API units
  * setTrigSensitivity(), setKeepSensitivity() - take int column value

- Implemented button handlers:
  * buttonStart() - calls sensor setSensor(eStartSen)
  * buttonStop() - calls sensor setSensor(eStopSen)
  * buttonSave() - calls sensor setSensor(eSaveParams)
  * buttonReset() - calls sensor setSensor(eResetSen)
  * buttonRestore() - calls sensor setSensor(eRecoverSen)

UNIT CONVERSIONS:
- Trigger Delay: API units 0.01s (0-200 = 0-2s) ↔ UI display in seconds
- Keep Delay: API units 0.5s (4-3000 = 2-1500s) ↔ UI display in seconds
- Distance ranges enforced:
  * Trigger distance: 240-2000 cm
  * Max distance: 240-2000 cm
  * Min distance: 30-2000 cm
  * Consistency checks: min ≤ trig ≤ max

INPUT VALIDATION:
- All text inputs validated with SafeString toFloat() conversion
- Invalid inputs logged to Serial for debugging
- Range limits enforced with auto-correction
- Slider inputs validated to 0-9 range

DWGS FILES UPDATED:
1. Dwg_TrigDistInput.cpp - calls setTrigDist(), displays getTrigDist()
2. Dwg_maxDistInput.cpp - calls setMaxDist(), displays getMaxDist()
3. Dwg_minDistInput.cpp - calls setMinDist(), displays getMinDist()
4. Dwg_keepDelayInput.cpp - calls setKeepDelay(), displays getKeepDelay()
5. Dwg_trigDelayInput.cpp - calls setTrigDelay(), displays getTrigDelay()
6. Dwg_keepSlider.cpp - calls setKeepSensitivity(), displays getKeepSensitivity()
7. Dwg_trigSlider.cpp - calls setTrigSensitivity(), displays getTrigSensitivity()
8. Dwg_buttonStart.cpp - calls buttonStart()
9. Dwg_buttonStop.cpp - calls buttonStop()
10. Dwg_buttonSave.cpp - calls buttonSave()
11. Dwg_buttonReset.cpp - calls buttonReset()
12. Dwg_buttonRestore.cpp - calls buttonRestore()

INO FILE UPDATES:
- C4001controls_serial.ino setup() method updated:
  * Added includes for C4001_SafeString_Wrapper.h and DFRobot_C4001.h
  * Created DFRobot_C4001_I2C sensor instance
  * Added C4001.begin() with error checking
  * Initialized wrapper with setSensor(&C4001)
  * Proper error loop if sensor fails to initialize
