Abstract:
Sensor Networks are designed for specific applications which range from
small-size healthcare systems to large scale environmental monitoring
systems. The design of sustainable sensor networks is a very challenging
issue. With the aid of rapid development of the modern technology,
commercial equipments for monitoring environment factors have been
introduced so frequently. However, the cost of these equipments becomes
the main problem when developing a sensor network. Also, energy
consumption of these equipment is another problem. In this paper, these
factors were considered and a sensor network implementation which uses
small low cost Linux board (Raspberry Pi) and low cost sensors was
introduced. A small microcontroller was used as the interface between the
sensor and the Linux Board and the functionality of this microcontroller
was also discussed. This was tested for recording CO2 content,
temperature and spectrum data. A practical method for continuous power
supply for the developed system was also described and application in
large scale environment was also proposed.
