WIRELESS NETWORKS
Precision agriculture aims to assist the
good management of our fields, bearing
in mind the differences in them
Soils.
Plants.
Climatology.
Field Orography.
Etc..
 The same field may have different
needs in different parts of it.
 We must know these differences and
and according to them sectorize field.
 About these homogeneous sectors,
extract information and based on it we
must make our policy decisions.
Good information will help us make better
decisions and thereby:
 Save in basic resources like water.
 Save in crop protection by knowing the
optimum time of application.
 As a result of the above will have a better
yield and minimize the impact on the
environment.
The experience is a very good
counselor but if accompanied with
technology.
Experience + Technology = Success
In the next slides we will see the available
technical equipment we have for
information on different variables of the
crop, how to get it into our base data and
software that acts as an intelligent
integrator of all measurements and
variables of interest which have been
monitored, with capacity and performance
management.
Sensors Registration
 Sensor measuring photosynthetic active radiation
 Solar radiation sensor
 Leaves moisture probe
 Dendrometers
 Humidity, conductivity and
soil temperature probe
Weather station with the following sensors:
 Temperature (inside and outside)
 Humidity (inside and outside)
 temperature thermal Integrals for pest control
 Wind (speed and direction)
 Blasts in 10 minutes
 Rainfall (0.2mm)
 Pressure
 Barometric trends
 Forecasts 24 hours view (text and icons)
 Several indices derived as the evapotranspiration.
 Moon Phase.
 Etc...
s SENSOR
SOIL MOISTURE
Pedí.
Soil moisture sensor , capacitive (FDR) which allows an economical solution to monitor our
soil, special design for easy installation in a wide variety are substrates providing a soil
moisture measurements of high quality and precision.
We can incorporate to this sensor an intelligent controller (right) that connects directly to
our irrigation system or a solenoid, scheduling the soil moisture based on the type of crop
will cancel irrigation if soil moisture is desired, stop the watering when it achieve this and
restart when the sensor indicates it.
s
Soil moisture multiple sensor
Pedí.
These capacitance probes (FDR) are designed to measure the moisture content of soil at
multiple depths (every 10 cm.) Deep-rooted plants, we have models to depths of 50 cm., 100
cm. and 150 cm.
For shallow-rooted crops such as grass have a 30 cm probe with multiple sensors (each 5
cm.) Accurately measures the impact and progress of the wetting front through the explored
profile between the roots , optimizing and improving irrigation performance, quality and
appearance of lawn
DENDROMETERS
Sturdy and easy to use equipments, record continuous
measurements of fruit growth and / or trunk and daily microfluctuations. Useful to know the water stress and optimize
irrigation.
s
Solar Radiation Sensor
Pedí.
Solar radiation sensor based on silicon photocell which collects the
most short-wave solar radiation useful to calculate the evolution
perspiration.
LEAF SENSOR of HUMIDITY
Determines the presence and duration of condensed water on the
leaf surface. It helps to control different pests, treatments, etc.
All this information can be received:
With analog handheld reader to view the data on the spot.
By WSN (wireless sensor network) capable of delivering all
information to a desired point in real time
REDES WSN
System designed to obtain, send and process data, consisting of
individual sensor nodes with energy self-sufficiency,
Each node takes measurements with a programmable interval,
and sent over the network to reach a sink node.
Depending on the resources available to the farm can be
connected to the computer to collect data, send them to a server
via Ethernet if you have internet access, or send via GPRS for
which all you need is to have phone coverage mobile.

ELEMENTS OF A WSN NETWORK
Sensors: They receive the desired environmental
information (humidity, temperature, etc..), and convert it into
electrical signal.
Sensor Node: Take the sensor data and send the
information directly or relying on other receiver / transmitter
nodes to the sink.
Gateway: Element interconnection between the sensor
network (sink node) and the base station (micro controller
with USB, Ethernet and GPRS).
Base Station: Collector ability to interpret data and act in
real time.
