Abstract :

The Rising Global Concern Regarding Womens Safety Necessitates The Transition From Reactive Mobile Applications To Proactive, Autonomous Wearable Hardware. This Research Introduces TechShield, An Advanced IoT-based Smart Gadget Designed To Provide A Continuous Safety Net Through The Integration Of Health Diagnostics And Real-time Security Alerts. Powered By The ESP32 Microcontroller, The Device Monitors Vital Physiological Parameters Using An SpO2 Sensor (blood Oxygen And Heart Rate) And A DHT11 Temperature Sensor, While Simultaneously Ensuring Physical Safety Through A Fall Detection Sensor And A Manual Panic Switch. The System Employs A Dual-communication Protocol: A GSM Module For Instant SMS Alerts Containing Precise GPS Coordinates, And An IoT Cloud Platform For Remote Dashboard Visualization. A Unique Feature Of TechShield Is Its Ability To Initiate Autonomous Emergency Alerts; If A Sudden Fall Or A Critical Health Anomaly (e.g., Tachycardia Or Hypoxia) Is Detected, The System Automatically Dispatches The Users Location To Pre-registered Guardians, Even If The User Is Unconscious Or Unable To React. Experimental Results Validate The Systems High Operational Reliability, Low Power Consumption, And Sub-3-second Alert Latency, Offering A Robust And Comprehensive Solution For Personal Protection And Wellness Management. Keywords: Womens Safety, ESP32, Wearable IoT, Fall Detection, GPS Tracking, SpO2 Monitoring, GSM Alerts
