Smart Wearable Device for Remote Health Monitoring and Emergency Location Tracking

Abstract

With the rapid advancement of wearable technology and Internet of Things (IoT), smart health monitoring systems have gained significant importance in providing continuous and remote patient care. This paper proposes the design and development of a Smart Watch for Tracking and Health Monitoring using LoRa Communication and IoT, aimed at real-time monitoring of vital health parameters and emergency location tracking over long distances with low power consumption. The transmitter side of the system is integrated into a smart wearable watch unit built around an Arduino Nano microcontroller. It incorporates multiple sensors including a heart rate sensor for monitoring pulse rate, a body temperature sensor for detecting abnormal temperature variations, and a MEMS accelerometer sensor for motion and fall detection. An emergency push button is provided to allow the user to instantly send distress alerts during critical situations. A GPS module is interfaced to obtain real-time location coordinates of the user. All sensor data and location information are transmitted wirelessly using a LoRa (Long Range) communication module, enabling reliable data transmission over long distances with minimal power usage. On the receiver side, a Node MCU (ESP8266/ESP32) microcontroller is interfaced with a LoRa receiver module to collect the transmitted data. The received health parameters and GPS location details are processed and uploaded to a cloud-based IoT platform, enabling real-time data visualization, storage, and remote monitoring through web or mobile dashboards. In emergency scenarios, alerts along with location details can be accessed instantly by caregivers or medical personal. The proposed system offers a cost-effective, low-power, and long-range health monitoring solution, making it suitable for elderly care, remote patient monitoring, outdoor workers, and emergency response applications. By combining wearable sensing, LoRa communication, and IoT technologies, the system enhances healthcare accessibility and ensures timely medical intervention.
