IoT Based Remote Health Monitoring System for Patients and Elderly People

The advancement of the Internet of Things technology is playing a key role in developing the health sector by making it much more accessible and affordable through easy to use applications for virtual and distant interactions with patients. Taking the capability of IoT technology into account, it is possible to overcome the difficulties faced by physically unstable patients in consulting a doctor physically on a regular basis. This work has led to a prototype of IoT Based Remote Health Monitoring System for Patients. This prototype consists of three health sensors: heart pulse sensor, body temperature sensor and galvanic skin response sensor. All these sensors were merged together into a single system with Arduino Uno and Raspberry Pi combined together. The data acquired from the sensors is transferred to a cloud storage via the Raspberry Pi. The cloud storage is continuously being updated in real time database. An Android Application was developed using Android Studio which could access the database and show a graphical representation of the health parameters. IoT integrated with the health wearables can overcome the need of visiting hospitals for primary health issues. This also reduces the medical expenses for patients significantly. In addition, the doctors can prescribe necessary medications by observing the patient’s health stats over time through an application. Detailed analysis of the signals was obtained with respect to variations in physical and environmental activities to understand the functioning of the sensors used.
