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 life-threatening 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 third-world countries, this problem is even more intense. For demonstration purpose, heart-rate and body temperature of a person is determined and rendered over the internet. Health data is uploaded in real-time 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 life-threatening situations. It can also be used for remote patient monitoring of regular patients of a doctor.
