The main aim of this paper to explore the potential of Wireless Sensor Networks (WSNs) technology in agriculture, which can help
to replace some of the traditional methods of farming and improves decision making. There are immense application of WSNs for
collecting, storing and analyzing or sharing sensed data. They can be used for various applications like habitat monitoring, agriculture, nuclear
reactor control, security and tactical surveillances. In this project, there are several external sensors like soil moisture, atmospheric
pressure, leaf wetness, soil pH sensors attached. Depending on the value of soil moisture sensor, the system will trigger the water sprinklers at
the time of water scarcity. When there is sufficient water, the sprinkler will be turned off. This will also conserve the water. Also, system will
sent the value of soil pH to the base station which will inform the farmer about the soil pH via SMS using GSM modem. This will help the
farmer to select necessary fertilizers which in turn prevents excess use of fertilizers. This will provide a helping hand to the farmers in
real-time monitoring, achieving precision agriculture and hence increasing the production by overcoming the problems faced due to lack of
proper knowledge about crop’s conditions and technical support. Thus, this system limits the problems of wired sensor networks and
has the advantage of flexible networking for monitoring equipment, simple installation and removing of equipment, low power consumption,
low cost and reliable nodes and high capacity.
