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/

3. WSN in Agriculture
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.

Architecture de una red WSN
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.
