Wearable Technology in Jacket for Tracking Person Health and Safety using IoT

This study presents the development of a smart wearable jacket designed for continuous health and safety monitoring using Internet of Things (IoT) technology. The system integrates multiple sensors to track vital parameters such as heart rate and body temperature, along with environmental factors like humidity and harmful gas presence. An ATmega328P microcontroller is used to process the collected data and evaluate it against predefined safety thresholds. To enhance emergency response, the system incorporates GPS and GSM modules, enabling real-time location tracking and instant alert transmission. When abnormal conditions are detected, the system triggers local alerts through a buzzer and simultaneously sends an emergency message with location details to predefine contacts. The proposed solution is compact, cost-effective, and user-friendly, making it suitable for industrial workers, elderly individuals, and outdoor users. Overall, the system offers a practical approach to improving personal safety through real-time monitoring and rapid response mechanisms.
