We developed architecture for a cloud based smart health monitoring system for peoples of Bangladesh. The system is low-cost, portable, and the sensor devices that are wirelessly connected to the central system, which is connected to a cloud. The cloud is used to store all information about the patients and diagnosis. We also developed intelligent algorithm to automatically screen different health parameters to perform basic diagnosis and make decisions. That will able to monitor health condition of individuals in rural areas where health services is inadequate. Health Workers run the system and provide basic health advice using cloud based medical system. In an advance and complex (in case of emergencies) health conditions the system will connect to specialist for expert opinions and also guide for next steps. The system uses wirelessly interconnected smart devices like computers, tablets, smart phones and medical instruments, sensors for measurements of different types of physiological parameters, which are also connected to a cloud for data storage and keeping health record. The system will perform regular health monitoring and create awareness on health. More importantly it will help to prevent worse consequences on health. We are planning to sell smart health monitoring system kit and provide medical health record services.
