It is crucial to defend women in today's world. In times of crisis, the IoT-based women's safety device described in this study is designed to provide real-time assistance and emergency reaction. Among the many safety features of the gadget are an automatic SMS warning system that alerts pre-saved contacts, a buzzer that alerts anybody around, and an auto-dial feature that allows the victim to speak hands-free with a designated contact. A shockwave generator included inside the gadget can render an attacker momentarily incapacitated, allowing the victim to escape. The hardware includes a Li-ion battery (3.7V, 2200mAh) with a TP4056 charger module for portability and prolonged usage, an Arduino Nano, a GPS Neo 6M module for realtime position tracking, a GSM SIM800L module for communication, and a 5V step-up power module. The 1000 KV step-up power module activates the self-defense shockwave capabilities. Combining these technologies, the proposed device provides a portable, reliable, and efficient solution for women's safety, offering immediate emergency assistance and deterrence.
