This paper introduces an intelligent safety life jacket enhanced with Long Range (LoRa) technology to address the pressing need for improved water safety measures. The proposed life jacket integrates cutting-edge features to offer a comprehensive safety solution for both recreational users and professionals in aquatic environments. Key functionalities include automatic inflation upon immersion, GPS-based location tracking, and real-time monitoring of vital signs through embedded biometric sensors. Leveraging LoRa technology enables the life jacket to transmit distress signals over extended distances, facilitating swift and precise rescue operations. Additionally, machine learning algorithms are employed to analyze sensor data, enabling the detection of potential emergencies such as sudden immersion or irregularities in vital signs. This proactive approach enhances safety by enabling early intervention and accident prevention. Overall, the integration of intelligent features with LoRa technology represents a significant advancement in water safety, with the potential to save lives and elevate safety standards in aquatic activities worldwide. These capabilities are also applicable to water accident scenarios where individuals immersed in cold water face similar risks of hypothermia, and this device could provide crucial monitoring and alert capabilities in such situations.
