NavyGuard Pro: Real-Time Health and Location Monitoring for Offshore Crews with NodeMCU ESP32

A small device called NA VYGUARD PRO is used to track crew members' location and health and instantly predict drowning conditions during offshore operations. The routine process of finding drowned sailors, especially in poor visibility or adverse weather conditions such as monsoon rains, is manual and risky for search teams. The solution uses a wearable bracelet with GPS tracking, an ECG sensor, and a Node MCU microcontroller to track location and health. By analyzing changes in the distance between the wearable device and the ship's Node MCU, the system can predict the situation on the ship, make it increasingly faster, and ultimately increase safety at sea and save lives.
