Abstract – Women’s safety has become an important societal issue due to the rising number of incidents related to
harassment and physical assault. This work proposes an IoT-based women’s safety device designed to deliver instant emergency assistance without incorporating GPS technology. The system prioritizes fast alert generation and dependable communication to ensure prompt support during dangerous situations. A microcontroller functions as the main control unit and is connected to input components such as a panic switch, motion sensor, and sound sensor for identifying emergency conditions. When a distress signal is detected, the device immediately transmits alert notifications to pre-registered contacts and emergency services through GSM or Wi-Fi communication. In the absence of GPS, the system utilizes network-based identification, user-defined location references, or proximity information to convey the user’s approximate position. Cloud integration allows secure storage of alert data and event records for future analysis. A dedicated mobile application provides real-time notifications and system monitoring features. The proposed device is lightweight, portable, and optimized for low power consumption, making it suitable for everyday usage. By removing GPS dependency, the system minimizes hardware complexity, reduces energy usage, and lowers overall cost while maintaining effective emergency response. This approach strengthens personal safety and offers a reliable IoT-enabled solution for improving women’s security
INTRODUCTION The safety of women has emerged as a critical concern due to the increasing number of incidents involving harassment, abuse, and violence in both public and private environments. Existing safety mechanisms often depend heavily on location tracking technologies, which may increase system cost, power consumption, and operational complexity. Recent advancements in the Internet of Things (IoT) have enabled the development of smart, connected devices that can provide rapid assistance without relying solely on GPS-based solutions. This research introduces an IoT-based women’s safety device designed to operate effectively without GPS integration. The proposed system emphasizes immediate alert generation, reliable wireless communication, and intelligent sensor-based detection of emergency situations. A central processing unit monitors inputs from panic buttons, motion sensors, and sound sensors to identify distress conditions.
1.1 Research Objectives The main objectives of this research project are: To design and develop an IoT-based women’s safety device that operates effectively without relying on GPS technology. To implement a rapid emergency alert mechanism using GSM or Wi-Fi communication for immediate notification. To integrate sensor-based inputs such as panic buttons, motion sensors, and sound sensors for reliable detection of distress situations. To utilize network-based or user-defined location references as an alternative to GPS-based tracking. To ensure low power consumption, reduced system cost, and improved usability for everyday safety applications.
1.2 Operational Modes
Normal Monitoring Mode In this mode, the device remains active and continuously monitors inputs from sensors such as the panic button, motion sensor, and sound sensor. Power-efficient operation is maintained to ensure long battery life during regular usage. Manual Emergency Mode This mode is activated when the user presses the panic button. The system immediately recognizes the distress signal and prepares the alert mechanism for emergency communication. Sensor-Triggered Emergency Mode The device automatically enters this mode when abnormal movement patterns or distress sounds are detected. This allows emergency activation even when the user is unable to manually trigger the system.
