Abstract:
       Sensors are the essential device for precision agricultural applications. WSN can
eliminate the cost of installation, maintenance and eliminates connectors. Potential benefits
includes fewer catastrophic failures, conservation of natural resources, improved manufacturing
productivity, improved emergency response, and enhanced homeland security. The ideal WSN is
networked and scalable, consumes very little power, is smart and software programmable,
capable of fast data acquisition ,reliable and accurate over the long term, costs little to purchase
and install, and requires no real maintenance. Selecting the optimum sensors and wireless
communications link requires knowledge of the application and problem definition. Battery life,
sensor update rates, and size are all major design considerations.
Existing system:
       In the traditional system, there is no alerting system, to alert the farmer about the
abnormalities in the important parameter for agriculture field. For each and every time the farmer
has to go to the field and monitor the agricultural parameters. This makes the farmer
inconvenience. We are in need of effective system to monitor the paddy crop.

Proposed system:
       In this project we discussing about updating agriculture parameter from paddy crop, here
we implement ARM7 Microprocessor, multiple sensor are like temperature, humidity and water
level sensor, Zigbee wireless and GSM modem. We update the parameter result from the sensor
node with the inbuilt ADC in ARM controller and then data is transferred to the zigbee to
another end to monitor in PC. From the PC, the sensor values are updated in the Internet. So the
farmer may their sites to know the status of their agricultural field. If the sensor values have
reached the threshold value means ARM processor indicates alarm and intimated to the Farmer
with the help of GSM Modem. Through this kind of automation we can acquire the Real time
field Monitoring system.
