How utkarshshinde873-ui/sos-device-for-womens-and-elderly-safety works
This is a small Arduino SOS device. A button press triggers firmware to obtain GPS coordinates and use a GSM module to send an SMS to predefined contacts; an emergency call is optional. The repository contains only the Arduino sketch, and no source excerpt was provided, so relationships reflect the README rather than inspected implementation details.
