Smart Healthcare is one of the key application fields for the Internet-of-Thing technologies, and home health tracking system is an important component for the realization of it. Based on the open source hardware platform Raspberry Pi and Arduino, this paper designs and implements a home healthcare tracking system. It uses Arduino to collect the physical health data from sensors and transmit the data with Bluetooth, then the collected data is analyzed in QT on the Rasperry Pi platform. Finally, the analyzed health status result is visualized in an LCD screen. We verified the feasibility and effectiveness of the system through the implementation of a prototype system and the extensive test based on it. The home healthcare tracking system is simple to use, extensible and of low cost, which is the solid basis for the realization of smart healthcare.
