Irrigation process is nothing but a cultivation of agricultural crops during the inadequate rainfall. And also it is used to maintain the landscapes. Now a days, irrigation process to the crops are very difficult and the farmers facing lot of problems to get the good quality of crops because of providing the sufficient quantity of water with the precious time feed to the crops is most difficult task. This problem can be overcome by automatic irrigation system. In recent years, lot of researchers focusing towards the automatic irrigation for helping to reduce the burden of farmers and also they are focusing about to properly cultivate the crops with the proper time period. In this proposed work, by using the arduino uno, the automatic irrigation process is done in effectively. With the additional accessories and components along with the arduino such as moisture sensor, solenoid value, relay modules and adapter provides the effective irrigation system. This proposed system is focusing to feed the necessary water to the crops based on its natural character automatically by the arduino code of the system. Also it protects the farmers against the injury causes due to harmful insects in the agriculture land when working in night.
