3. Soils. Plants. Climatology. Field Orography. Etc.. Precision agriculture aims to assist the good management of our fields, bearing in mind the differences in them

4.  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.

5. 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.

6. The experience is a very good counselor but if accompanied with technology. Experience + Technology = Success

7. 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.

8. Sensors Registration  Sensor measuring photosynthetic active radiation  Solar radiation sensor  Leaves moisture probe  Dendrometers  Humidity, conductivity and soil temperature probe

9.  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... Weather station with the following sensors:

10. SOIL MOISTURE SENSOR 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. Pedí. s

11. Soil moisture multiple sensor 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 Pedí. s

12. DENDROMETERS Sturdy and easy to use equipments, record continuous measurements of fruit growth and / or trunk and daily micro- fluctuations. Useful to know the water stress and optimize irrigation.

13. Solar Radiation Sensor Pedí. s Solar radiation sensor based on silicon photocell which collects the most short-wave solar radiation useful to calculate the evolution perspiration.

14. LEAF SENSOR of HUMIDITY Determines the presence and duration of condensed water on the leaf surface. It helps to control different pests, treatments, etc.

15. 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

16. 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.

18. 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.
