2. WSN in Agriculture
Introduction:
 WSN is an acronym for Wireless Sensor
Network
 Each node of the network is called MOTA
 They communicate among themselves and
with a gateway
 This gateway can be reached from Internet
 Manufacturers:
 CrossBow: http://www.xbow.com
 Libelium: http://www.libelium.com/

 Mesh networks: http://www.tranzeo.com

Aplications:
 Deployment of such distributed
sensor networks offers several
advantages:
● Diversity, scalability and higher
density as compared to spatial
centralized
● Self-organizing robust networks

4. WSN in Agriculture
Components:
 The Battery currently have an
estimated life of up to 1 year. They
are usually Nickel Cadmium
batteries.
 Microprocessor: the speed is often
of several megahertz and
has a fairly low RAM
(about 256 Kbytes to
256 Kbytes RAM
and others to EEPROM).
 The Battery currently have an
estimated life of up to 1 year.
They are usually Nickel
Cadmium batteries.
 Also used solar panels embedded
with specks

5. WSN in Agriculture
Components (cont.)
● The radio: IEEE 802.15.4 and
Zigbee (future de facto standard
that combines IEEE 802.15.4 and
HomeRFLite above) are the most
used
● Sensors: are becoming smaller,
more powerful and consume less
energy.
● Software:
● Arduino / Processing to control
spots
● You can also use the NESC language
(similar to the C language) on
embedded operating systems like
TinyOS.

 Wireless networks of motes perform
a self-organizing communication
 They pass their sensory input
and information they receive
from neighboring spots to other
spots until it reaches the
gateway.

measured
 Connecting to a database for storing
parameters, historical consultation, etc.
 Integration with statistical computing
software such as VESPA
 Geostatistical analysis by interpolation of
the measured points (Kriging)

10. WSN in Agriculture
Limitations:
 The motes are components of very limited
resources: they have a small CPU and
limited storage capacity
 Communication bandwidth, limited.
 Their lifespan is determined by its ability to
conserve energy (not to waste the battery.)
 Normal state: in hibernation except when
making measurements and transmitting the
results

New aplications
 Vineyards / Wineries
 Farm animals
 E-health: measurement of body parameters in elderly
people
 Home Automation: Control lighting, temperature in
each room, etc.
