Real-time Location Tracker for Critical Health Patient using Arduino, GPS Neo6m and GSM Sim800L in Health Care

Internet of Things (IoT) is the technology that helps in communication between machines, circuits, and different types of devices. This feature has applications in the health care industry to benefit as sensors, actuators, and hardware support the technology behind IoT. In the health care sector, in case of an emergency, it is very crucial to know the exact location of the patient so that different critical health care services can be made available at the right time and place. This problem can be solved by using GPS coordinates. In this paper, an IoT device is made which locates the exact GPS coordinates of the patients to the server. Moreover, using the web interface on the server and Google Maps, doctors and hospital staff can track the exact location of the patient and serve him. This system made can also be used on wild animals, school students and transport services where the location is an essential parameter. The system is made using sensors like GPS Neo 6m, Arduino, GSM Sim800L. Here, different IoT platforms, Different IoT tools, sensors, different programming libraries, APIs usages, server hosting and needed AT commands with website interface are implemented and discussed in detail to make a low-cost GPS tracker.
