ABSTRACT
Sensors are the hopeful device for precision agriculture. By
forming wireless sensor network we can make good monitoring
system in the paddy crop field area. This paper proposed
idea about monitoring the crop field area without man power.
The fundamental concept of this paper is to provide a highly
enabled monitoring of paddy crop field. In this paper we have
detailed about how to utilize the sensors in paddy crop field
area and explained about Wireless Sensor Network
(WSN), Zigbee technology, Protocol stack of zigbee. We
checked out the zigbee technology with two different
commercial modules (Xbow and Xbee).We did the analysis of
battery life under sensor deployed in the water conditions and
the evaluation of the reliability of communications and
measurements.
Zigbee Technology
Zigbee is mainly famous for its mesh topology. In this crop field
monitoring we used mesh topology. The various sensed data
from various sensors goes to the central Global System for
Mobile (GSM) node. From that the sensed data is given to the
personal computer, which is used by a farmer [2], [3].Zigbee
is a low power wireless sensor network technology based
on IEEE 802.15 Zigbee operates in the industrial, scientific and
medical(ISM) radio bands. In paddy crop field monitoring we
used 2.4 GHZ operating frequency nodes for study purpose.
INTRODUCTION
Wireless Sensor Network
Wireless sensor network is a network in which several types of
sensor nodes are deployed. Wireless sensor network is scalable
and consumes very little power, software programmable and
fast data acquisition. A WSN (wireless sensor network)
generally consists of base station (or) gateway that can
communicate with a number of wireless sensors via a radio
link. WSN can eliminate the cost of installation, maintenance
and eliminates connectors [1].Wireless sensor networks are
used in many applications such as environmental monitoring,
habitat monitoring military surveillance, inventory, tracking,
smart spaces and all. Wireless sensor networks are essential for
monitoring the agricultural field area, such as paddy crop field
area, fruit field area for get real time datas. Gateway is used for
to connect separate networks. By using wireless sensor
network we can get real time datas such as temperature,
pressure, humidity.
Flow Chart
In paddy crop field we have to irrigate the water full area of the
land. After some periods of farming it is not need to irrigate the
water fully to the crop field land .We have to irrigate the water
depending upon the soil, ups and downs of the land and have to
irrigate the water where it needs. In present era there is no
mechanism for Irrigate the water where it will be need. In this
project we make zigbee wireless sensor network for monitoring
the crop field area by deploying water sensors in the land and
detect the places, where the water level is low[4].
From those results we irrigate the water to that place only.
From the above methodology we can save the water and
minimize the problem of water logging in the land. We used
humidity sensor to sense the weather. From that the farmer can
get idea about the climate. If there is any chance arise for
rainfall farmer need not irrigate the water to the crop field. It
gets water from naturally by rainfall. Because of that we can
save the water and also power due to reduce the running of
motors [4].
