Abstract: Women’s safety and health monitoring have become critical challenges due to the increasing incidence of harassment and sudden medical emergencies. This paper presents Safe Guard Smart Bangle, an IoT-based wearable emergency system that integrates a panic alert mechanism with on-demand health monitoring. The system is developed using an arduinoUno microcontroller and incorporates an emergency panic button, NEO-6M GPS module, ESP8266 Wi-Fi module, heart rate (pulse) sensor, LM35 temperature sensor, and a buzzer. When the panic button is pressed, the buzzer generates an audible alert to notify nearby individuals, while the system simultaneouslyacquires the user’s real-time location along with heart rate and body temperature data. The collected information is transmitted to an IoT cloud platform for monitoring and storage, and an emergency alert message containing the location and health parameters is sent to a Telegram Safe Guard Bot. The proposed wearable device is compact, cost-effective, and energy-efficient, making it suitable for use in both urban and rural environments, and demonstrates the effectiveness of IoT-enabled wearable systems in enhancing emergency response for women’s safety and health support.
