Smart Wearable Wristband for Patients' Health Monitoring System through IoT

In today's modern world, technology takes part an important role in the medical field. It is must necessary to monitor the patient's health continuously after the operation of the patient. In the healthcare field Internet of Things (IoT) plays the main roleinmonitoring health with lots of applications. To monitor the health parameters of the patient, the smart wearable wristband monitoring system is implemented by using the IoT domain. In this article, the NodeMCU microcontroller act as a gateway between the hardware devices and the software. The parameters to be measured from the patient's body are temperature, heart rate, glucose level, oxygen level, and Blood Pressure (BP). These parameters are measured by using the sensors. The sensors are interfaced with the microcontroller. Then the microcontroller sends the data from the sensors to the cloud. The cloud will analyse the data from the normal values given in the microcontroller. If any of the parameter's data from the sensor are measured as abnormal values, the cloud will send the alert message and the location of the patient to the patient's relatives, to the doctor who is attending that patient, and to the patients' mobile via Global System for Mobile communication (GSM), and Global Positioning System (GPS) for location.
