Abstract: Women’s safety has become a significant social and technological concern, particularly in remote and rural regions where immediate communication during emergencies is often unreliable due to poor network connectivity. Most existing safety solutions depend on cellular networks, which may fail in such environments, creating a critical need for an alternative approach. This project proposes ResQHer, a smart women’s safety device that employs LoRa-based hybrid communication to ensure long-range, low-power, and reliable transmission of distress alerts even in areas with limited or no internet access. The system integrates an ESP32 microcontroller, a LoRa SX1278 module for long-distance communication, GPS for real-time location tracking, and GSM/Wi-Fi as backup channels. When the emergency trigger is activated, the device instantly sends alert messages along with precise location details to predefined contacts and a centralized monitoring gateway. Designed to be compact, wearable, and energy-efficient, the device is suitable for everyday use and supports future enhancements such as continuous tracking, data logging, and integration with emergency response services. Overall, ResQHer aims to improve women’s personal safety by enabling faster assistance, dependable communication, and enhanced situational awareness across both urban and rural environments.
