IoT Based Remote Medical Diagnosis System Using NodeMCU Internet of Things (IoT) can help us better our lives in many ways by rendering real time information over the internet collected from a smart network of devices. In this paper, we have discussed about Remote Medical Diagnosis System (RMDS), which can come to aid for humans in many lifethreatening situations. Often, people fall sick in locations where there are no hospitals or healthcare facility nearby, in such cases people sometimes even die due to lack of proper treatment and diagnosis. In rural areas of thirdworld countries, this problem is even more intense. For demonstration purpose, heartrate and body temperature of a person is determined and rendered over the internet. Health data is uploaded in realtime and can be viewed through a web browser. The aim of RMDS is to remotely provide health information of a patient to a healthcare professional in lifethreatening situations. It can also be used for remote patient monitoring of regular patients of a doctor.

Understanding Ehealth Application Utilizing Internet of Things (IoT) Technologies EHealth applications make room for exchange of information between medical professionals and patients, hospitals to hospitals, lower cost, increased scope and extent of medical facilities, as well as improving the quality of services. Despite all these advantages, healthcare system is still being challenged with the factors such as increased number of ageing population, need for reduced cost of health services, the shifting of healthcare services from providercentric to patientcentric, the type of new diseases available and their treatments. All these require Internet of Things (IoT) for its transformation. This work seek to explore Internet of Things in eHealth domain and determine how its operations can transform healthcare application system. We examined technological and application trends in healthcare, Convergent eHealthIoT Works, attacks and issues in eHealth utilizing Internet of Things technologies, applications of Internet of Things (IoT) in eHealth, as well as challenges and open problems in the eHealth domain.
