The World Health Organization (WHO) in their statistical report on 2018 stated that the heart and pulmonary diseases are continuing to be at the top global causes of death. These diseases are known as non- communicable diseases (NCD) as it progresses slowly and exists for long duration of time.

The continuous monitoring of crucial signs of human body like heart rate, blood oxygen level, blood pressure and blood glucose level assists in timely discovery and also provides room for the proposed treatment. Evolution of technologies like wireless sensor network, embedded systems, computing and storage which are grouped under the name of one umbrella technology called as ‘Internet of Things’ (IoT), brought various health trackers that monitors the physiological measures of human and also keep track of their daily activities in real without the need of the person to be in hospital, but those measures are updated to the medical experts concern time-to-time for their valuable suggestions and follow-ups.
