IoT-Powered Emergency Button for Women's Safety

Abstract

In a world where women's safety remains a major concern, there is an urgent need for proactive solutions that can provide real-time assistance during emergencies. Traditional mobile applications and emergency contact numbers, while useful, rely heavily on user interaction and internet connectivity, which may not always be accessible in high-stress situations. This project proposes a practical, standalone, and IoT-based solution titled "IoT Powered Emergency Button for Women Safety", designed to address these limitations.
The system consists of a compact and wearable emergency switch built using an ESP8266/ESP32 microcontroller, a NEO-6M GPS module, and a SIM800L GSM module. A simple push button serves as the trigger. When pressed, it activates the system to retrieve real-time location coordinates and send an SMS alert containing a Google Maps location link to pre-configured emergency contacts. A buzzer or LED indicator provides immediate feedback to the user, confirming successful transmission of the alert. The system also integrates Blynk IoT platform support, enabling cloud-based monitoring, logging, and app-based notifications.
The prototype was successfully tested under various real-world conditions, including weak GPS signals and GSM network fluctuations. It demonstrated high reliability in sending alerts, maintaining GPS accuracy, and functioning effectively even without internet access. The system is energy-efficient, battery-powered, and fully portable, making it suitable for everyday use as a wearable accessory.
This project contributes to the domain of smart safety systems by offering a low-cost, independent, and easy-to-use device for women’s personal security. Future improvements such as two-way communication, battery monitoring, fall detection, and mobile app integration are also discussed, paving the way for a scalable, real-world deployment. The integration of embedded systems and IoT technologies into safety applications proves to be a powerful step toward building a safer, more responsive environment for women.
