Development of IoT based Health Monitoring System for Disables using Microcontroller

Health monitoring system in general is an innovation which is adopted worldwide especially in the last decade. The Patients suffering from permanent disables are much required to monitor them for their survival. Such patients are facing lot of issues because in no time their health is at risk. It is very difficult to predict them as there is a need of nursing all the time too. This paper presents a mobile phone linked health monitoring device programmed and controlled by Internet of Things (IoT). The important takeaway is to provide a handheld support for the healthcare professionals can monitor or to be notified when they are even outside the hospital environment to ensure the safety of the disable patients. The sensors collect the necessary information which is been sent to the IoT server and linked with the Internet module. The system consists of sensory devices, data acquisition system (DAQ), a controller (ESP32) and a software application. The body temperature, heat rate per minute, Heart ECG, oxygen level and Blood pressure are constantly monitored and stored as a report. The same report has been sent to the professionals, mobile phone through developed IoT application. Additionally, a text message is sent to the senior doctors' mobile phone if the sensor data exceeds the threshold value. Therefore, a mobile phone linked health monitoring system for disable patients constantly monitor and notify the concerned person on time and save precious life.
