🚀 Installation

Prerequisites

• PlatformIO IDE or Arduino IDE
• ESP32 development board support
• Required libraries (see platformio.ini or libraries.txt)

Setup

1. Clone this repository:

   git clone https://github.com/username/smart-safety-jacket.git

2. Open the project in PlatformIO IDE or Arduino IDE

3. Install the required libraries:

   • For PlatformIO: Libraries will be automatically installed
   • For Arduino IDE: Install libraries manually through Library Manager

4. Configure your device:

   • Edit include/config.h with your specific settings
   • Adjust sensor calibration values if needed

5. Upload the firmware to your ESP32:

   # For PlatformIO
   pio run --target upload

6. Open the Serial Monitor to verify the device is working correctly

📱 Usage

1. Power on the jacket by pressing the power button (located inside the chest pocket)

2. The jacket will perform a self-test sequence:

   • LEDs will flash
   • Buzzer will sound briefly
   • Vibration motor will activate

3. Connect your mobile device to the jacket via Bluetooth:

   • Open the companion app
   • Select "Smart Safety Jacket" from the device list
   • Wait for connection to establish

4. The jacket will now:

   • Continuously monitor environmental conditions
   • Track your health metrics
   • Alert you to potential hazards
   • Send data to the mobile app

5. To charge the jacket:

   • Connect the USB-C cable to the hidden charging port
   • The LED indicator will show charging status
   • A full charge takes approximately 3 hours

📲 Mobile App

The companion mobile app provides:

• Real-time monitoring of all sensor data
• Historical data visualization
• Customizable alert thresholds
• Emergency contact configuration
• Location tracking (when GPS module is installed)

Download the app from:

• Google Play Store (Android)
• App Store (iOS)

🔮 Future Enhancements

• GPS + LoRa integration for remote location tracking
• Thermal fabric patches for internal overheating detection
• OLED display on chest for status information
• Machine learning for improved hazard prediction
• Voice control and feedback system
• Integration with industrial safety management systems
