In the field of agriculture, the crop yield is getting reduced by the attacks of wild animals. It is mandatory to prevent the animals to not to enter agricultural lands. Farmers are suffering a lot by the animal attack. Sometimes people also lost their lives while they try to send the animals out of their place. The animals enter into the agricultural land because of the lack of water resources in the forest areas and deforestation. In this project, we propose a method to protect farms from wild animals via ubiquitous wired network devices, which is applied to farm along with traditional methods to improve the protection performance. Operational amplifier circuits are utilized mainly for the detection of animal intrusion from the outside of farms. The proposed monitoring scheme is to provide an early warning about possible intrusion and damage by wild animals.
