Nowadays, penetration of the Internet of Things (IoT) technology was spread in various domains. One of the promising business domains of IoT adoption is healthcare. With the vast amount and variance of smart wearable device based on IoT principles on the market, a consumer could easily find equipment to track their health status (i.e., blood pressure, heart rate, body temperature, etc.). But, those devices have two drawbacks. First, the significant cost of investment was required for implementing those devices on a massive scale (i.e., patient monitoring in a hospital). The second drawback is the lack of platform which can efficiently manage multiple devices concerning storing and organizing the data generated by those wearable devices. In this paper, we introduced a cost-efficient design of healthcare monitoring system based on IoT technology. This design proposed holistic approach from providing less expensive hardware for sensing purposes and a sub-platform for managing acquired data from sensing activity based on big data technology.
