A Comparative Study on Modern Smart Irrigation System and Monitoring the Field by using IOT

India is generally reliant on Agriculture yet there are fast changes in its storm. Presently a day's level of groundwater, Hybrid Breeding, Quality of Fertilization is going down. According to record step by step populace is expanding in India and interest for sustenance is likewise expanding all the while. Our economy is predominantly in light of the market of Agriculture. Water is the primary asset for horticulture. Consequently productive water administration of freshwater assets has a critical significance. To spare the water and to expand the yield of product, appropriate technique for water system must be utilized. According to audit of a few papers, there are diverse sorts of procedures and frameworks that are utilized to control the wastage of water and screen the water system framework in a robotized way. The framework incorporates the remote sensor system of soil dampness, temperature and moistness sensor are put into the field. The framework is intended to locate the correct field condition, to control the wastage of water in the field, to give correct controlling of the field by utilizing the programmed water system and programmed the farming condition by utilizing the parts that construct the fundamental equipment.
