Empowering women with advanced safety solutions, this wearable gadget addresses the growing need for personal protection. Due to rising incidents of violence and harassment, the proposed device sends a location alert to guardians and delivers an electric shock to deter assailants. It uses a heart rate sensor to detect sudden spikes in pulse that indicate distress. Upon detection, a 3 mA pulse inductor is activated to shock the attacker, while a Global Positioning System (GPS) module sends the wearer’s location via Short Message Service, enabling real-time tracking through Google Maps. Powered by a 3.7 V lithium-ion battery, the system includes an Arduino Uno, GPS module, pulse sensor, and relay. Designed to be compact, the device is envisioned for future integration into wearable accessories such as a watch.
