In high-risk environments, quick and discreet distress signalling is crucial for personal safety and emergency response. This paper presents the design and development of a smart and portable emergency distress signal device that offers signalling modes for diverse emergency scenarios. The objective is to design a covert emergency signal device for soldiers, spies, and individuals in high-risk environments. This device allows the soldiers in war zones to send SOS signals to rescue teams for rescue operation. This device's Single-Click activation mechanism enables rapid distress signalling, including GPS alerts and LED flashes along with buzzer activation, while allowing silent SOS transmission with a double click where buzzer is turned off. A long press deactivates the device, ensuring user control. The GPS module allows the device to send the soldier's real-time location when activated and updates every few minutes. This is useful for rescue teams to locate the soldier in danger quickly. This Lightweight, Portable device utilizes Arduino Uno, a small buzzer, and an LED, making it cost-effective and easy to build. By eliminating the need for radio signals, this system enhances covert communication and emergency signalling, particularly in war zones and undercover missions. This paper discusses the device's technical implementation, hardware-software integration, and real-world applications, demonstrating its potential to enhance safety, security, and emergency preparedness.
