Health Care Monitoring System Based-on Internet of Things

Abstract

The development of technology in the era of the industrial revolution 4.0 have led to the emergence of the Internet of Things (IoT). IoT allows an electronic devices to send and capture data through the internet and provides more methods of data interoperability. Nowadays, IoT plays an important role not only in communication, but also in monitoring, recording, storage and display. Currently, the application of IoT in health monitoring system to monitor conditions in the vital signs of the human body becomes interesting issues as an effort to prevent disease. In this article, a system that can monitor vital sign parameters and transmits data through wireless communication was developed, then those data transferred to the network via Wi-Fi modules. Data can be accessed at any time and represent the patient's current condition. So that a nurse or doctor can monitor the patient's data in real time through an application software on smartphone. Overall the system developed consists of DFRobot Firebeetle ESP32 as a controller that has been equipped with Wi-Fi modules, Sensor MAX30100 as a pulse detector and MLX90614 sensor as a body temperature detector. Also added is a GPS (Global Positioning System) module to detect patient locations in real time and an OLED (Organic light-emitting diode) module as data viewer. The test results show that the overall system was worked properly with a 6.5% error for pulse detection, 4% for oxygen detection and 1.7% for body temperature. As for the accuracy of the position generated by GPS that is 7 meters.
