Every living organism needs food to llue, We cannot imagine life without Irrigation. If everything gets automated even irrigation systems also need to be. We have developed a Smart Irrigation system using the concept of loT. As we know farming has different stages, To help these farmers in understanding the climatic conditions, the maisture content in the soil and to make their decisions easy we have developed Smart Irrigation System using lot. We used different sensors that sense temperature, moisture and humidity of the agricultural area. Information on all sensor nodes is collected by the ZigBee module and transmits the data to microcontroller connected with the wifi module that uploads the report on the cloud where a farmer can monitor those parameters in their Smartphones or PC on daily basis and take necessary steps to make their agriculture farm grow smart
