SOS-Enabled Wearable for Personal Security with GPS Tracking and Fall Detection

Smart wearable IoT device is a comprehensive solution designed to increase the safety of women and old aged people by leveraging the GSM and GPS. The microcontroller ESP32 works as the central processing unit and manages various modules such as GPS tracking, GSM communication, and motion sensing. The device features an SOS panic button that can be manually activated in distress situations, automatically triggering SMS and call alerts to predefined contacts which is set by the wearable device admin can get the user’s current location, even in offline scenarios. To enhance its safety feature further, the device has an accelerometer and gyroscope (MPU6050) for fall detection. The sensors monitor sudden movement, jerking, or prolonged stationary time, triggering automatic alerts in presumed danger scenarios. A voice recording module is optionally provided to capture audio evidence in case of emergencies for post-incident analysis. The system is also able to run on a rechargeable lithium-ion battery, supported by an energy-efficient power management circuit that provides energy efficiency and extended operation. Low power consumption, USB charging or optional solar charging, and battery level indicators make the device more accessible and portable. Future releases will introduce AI-driven threat detection, geofencing alerts for location-based safety triggers, and biometric authentication to avoid unauthorized use. This intelligent wearable device is a fresh, affordable, and easy solution responding to the urgent need for active personal protection in the fast-changing technology world.
