Health Monitoring Using Smartwatch

The proposed wearable device integrates sensors for heart rate and body temperature, along with BMP180 and MPU6050 modules, interfaced with the NodeMCU ESP8266 microcontroller. Sensor data are processed locally and transmitted wirelessly via Wi-Fi to a Firebase database. The system enables real-time visualization of vital signs through an Android application, offering notifications to both users and administrators based on critical health conditions. By combining mobility, low power consumption, and immediate feedback, this implementation enhances remote health monitoring and provides a proactive approach for personal healthcare management. The results demonstrate the feasibility of continuous monitoring and timely alerts, emphasizing its potential for improved healthcare accessibility and preventive interventions.
