Abstract: Women’s safety has become a major concern globally due to increasing incidents of harassment and violence. This paper presents an IoT-based smart wearable emergency safety system designed using an ESP32 microcontroller, SIM800L GSM module, NEO-6M GPS module, and VC-02 voice recognition module. The system provides dual activation modes: manual (panic button) and voice based triggering. Upon activation, the device transmits real-time location coordinates via SMS to predefined contacts. The proposed solution operates without internet connectivity, ensuring reliability in remote areas. Experimental validation shows quick response time, accurate location tracking (~2.5 m), and reliable alert delivery. The system is cost-effective, compact, and suitable for daily wearable use.
