AGRICULTURE CYCLE .ADVANTAGES.CONCLUSION.

A wireless sensor network is a collection of nodes organized into a cooperative network.Each node consists of processing capability may contain multiple types of memory have an RF transceiver, have a power source (e.g., batteries and solar cells), and accommodate various sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants, at different locations.

WIRELESS SENSOR NETWORKS

COMPONENTS OF SENSOR NODES

TRANSMISSION MEDIAIn a sensor network,

communicating nodes are linked by a wireless medium. To enable global operation, the chosen transmission medium must be available worldwide.

RadioInfrared optical media.

Why wsN IN AGRICULTURE ?

Agriculture is the most prominent sectors in every country economy. For example, about 43 % of India's geographical area is used for agricultural activity. The contributions of agriculture sectors in the Indian GDP for 2008-2009 is just 17%.. The current level of data collection is not efficient and sufficient. Sensor network technology helps in obtaining data in real time mode.

Crop management .Irrigation management.

Why wsN IN AGRICULTURE ?Crop management:

WSN’s can play a key role in crop management. Wireless sensor was to be used to detect leaf wetness the data could be sent in real time to the farmer or decision maker. Irrigation Management: Efficient irrigation management is vital for successful crop growing.. However, a WSN can facilitate Monitoring of moisture levels for crops and, in conjunction with an actuator can take a decision as to when it is appropriate to perform irrigation. This method can reduce water use. In addition, Over-irrigation of crops can lead to nutrients being leached from the soil.

SENSOR avalable

•Air temperature.•Relative humidity.•Solar radiation.•Soil moisture and temperature in 3 deep.•Wind speed.•Leaf wetness.•Air pressure.•Co2 concentration.•N, P and k concentration in soil.

Wireless Lan WIRELESS LAN:

A wireless LAN provides a high speed transmission network for the data collected by Sensors.

CAMERADigital camera attached with the sensor will continuously monitor the crop.

WEB SENSORWeb server is software which gives web information to a client

We can access the web server by using web browser such as internet explorer.

POWER SOURCESSolar energy.

COMMERCIAL SENSOR

AGRICULTURE CYCLEBy the agriculture cycle we can increase the future harvest.

ADVANTAGES•We can conserve water and increase the Yield.•Sensors are very useful in irrigation Scheduling.•By knowing leaf wetness we can forecast the diseases.•By using web server we can provide information on pest and disease infection•Fertilizer should be applied at proper time and in proper quantity.•By using sensors, we can achieve very high application efficiency.

DisadvantagesCostIt is a project of span lab which is under research..

conclusionAgriculture is the predominant occupation. It is the most prominent sectors in every countries economy. Improving the product quality, managing resources efficiently by the use of WSN in precision agriculture. “In future the wide range of applications will make sensor networks an integral part of our lives”.
