In India, agriculture plays an influential role for development in food production and also for the economy and development of a country. In the agriculture’s field, use of proper method of irrigation plays a paramount role. Indian agriculture is mainly reliant on the monsoon which is not a reliable source of water. Therefore there is a need for a smart irrigation system in the country which can provide sufficient amount of water to the farms or fields according to their soil’s moisture content. Many areas of agricultural fields are effectively over or under irrigated due to spatial variability in water infiltration and runoff of rainfall and irrigation. Under-irrigated areas are subject to water stress, resulting in production loss, while over-irrigated areas suffer from plant disease and nutrient leaching. Relevant soil water level is a mandatory called for optimum plant growth. As, water is a prerequisite element for life sustenance, there is the necessity to avoid its undue usage. Irrigation is a dominant consumer of water, which consumes lot of groundwater. A need occurs to regulate water supply for irrigation purposes. In this model or project a trial has been made to automate farm or other irrigation’s fields (like garden, nursery etc.) that allows farmers to give sufficient amount of water using arduino. This work is best suit for those places where water quantity is scarce and where it should be used in a reserved quantity. Also, the other countries of the World can also afford this model. As it a simple project and results in a cheap solution for irrigation and obtain good yields crops production and will be an autonomous system. Beside irrigation this method can be used in homes (for garden, flower bed etc.). This module makes the irrigation system automated. With the use of sensors whose cost is low and with simple circuitry this experiment aims in low cost solution, which can be bought even by a poor farmer and it is also easy to implement.
