Abstract

To solve the problems of strong heterogeneity of equipment and platforms, and closure, tight coupling and weak extensibility of the platforms, we propose an architecture design of Internet of Things based on open source hardware. The architecture is designed in three domains, sensing domain based on open source hardware, network domain based on wired and wireless networks, and application domain based on database, web and server application. And three developing schemes of the sensing domain on Arduino, Raspberry Pi and combination of the two, are proposed and discussed in details respectively to satisfy different configuration and application requirement. At last, an application of humidity and temperature surveillance system based on this architecture is implemented, which verified the advantages of this architecture design: ubiquitous access for various sensors, ubiquity for network access, and good system extensibility, and was apt for fast development.
