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.

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.

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.

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”.
