• Abstract:

  Women’s Safety Remains A Major Issue In Today’s Society, Requiring Effective And Immediate Response Systems During Emergencies. This Project Presents A SmartPortable SOS Safety Keychain Designed To Provide Rapid Assistance When A User Is In Danger. The System Is Developed Using The ESP8266 SoC Microcontroller, Which Enables Wireless Communication And Real-time Alert Transmission.When The SOS Push Button Is Pressed, The Device Sends An Emergency Notification Along With The User’s Live Geographical Location Obtained Through The NEO-6M GPSmodule To Pre-configured Contacts. To Further Strengthen Security And Provide Evidence, The System Integrates A MAX9814 Microphone Module For Audio Recording And Includes A Buzzer For Alert Indication. The Recorded Data Can Be Stored In Memory And Accessed Remotely When Required.The Device Operates On A Rechargeable 7V Lithium-ion Battery, Ensuring Portability, Compact Design, And Low Power Consumption. Additionally, A 7-segment Display Is Incorporated For Status Indication. A Survey Conducted Within The Campus Indicated That Nearly Half Of The Students Were Unaware Of Existing SOS Safety Devices, Emphasizing The Necessity Of Implementing Such Smart Safety Solutions. The Proposed System Offers A Reliable, Portable And Efficient Approach To Enhance Women’s Personal Security Through Instant Alerting, Live Tracking, And Evidence Collection.
