Wireless sensor networks are networks of small, resource constrained sensor equipped computers called sensor node or node. It is considered that sensor networks will have many applications in future. Those networks work independently and need nearly no infrastructure while operating. For example sensor nodes with a movement detection sensor can form a network for area surveillance. Former research dealt with abstract simulation of such networks but recently, such nodes are available as real hardware. In the context of the TriSOS project such nodes were developed at the University of Applied Sciences in the CoSA research group. The TriSOS nodes design was inspired by the Atmel AVR Raven Evaluation Board.


For the Software development we use svn as a project repository. The Hardware/Software documentation is generated by the tool Doxygen automatically. The study projects aim is to figure out the differences in the hardware (e.g. pin configuration) between Atmel AVR Raven Evaluation Board and the TriSOS node and write it down. Furthermore it is mentioned to create figures (based on photos and schematics of the hardware) which show the detailed components of a node (sensors, display, LED's, ...). The results of this work will be part of the above mentioned project documentation.


  • A detailed report (at least eight pages) with a description of the work, the solution approach and also the differences in a table like manner and a Doxygen version with figures out all differences between the different hardware.
  • It is also necessary to create figures from photos of the hardware which show and explain the sensors and components. This figures are a part of the description and also the Doxygen documentation.
