Application

The DSYS25 has many applications ranging from traffic control to agriculture

Power

The DSYS25's power source is application specific, using either batteries or some other form of energy supply mechanisms such as solar cells.

Software

The DSYS25 uses TinyOS as its operating system as it is opensource and freely available. There is also a version of TinyOS specifically tailored to the DSYS25 platform. See TinyOS for DSYS25 for details.
