IoT Based Smart Irrigation System

The IoT-based smart irrigation system is used for optimizing use of water in the fields of agriculture. This irrigation method increases sustainability and is beneficial in areas with limited water supplies. Its threshold values can be changed to suit the needs of different crops that need to be irrigated. Water is pumped to each plant through drip irrigation, and fertilizers required for plants are also provided at certain points. A mobile application (app) can be used to get the data regarding water level, pH level, and the soil nutrient content. Farmer can use the app to check water and nutrient requirements. Data collected from the node is retrieved from the cloud and made available to the farmers through application. Two modes namely manual and automated can be made available to the user. In the manual mode, the farmer can remotely operate the motor and monitor the moisture sensor value, while in automated mode, the server takes the decision for turning the motor ON/OFF based on the logical comparison of moisture sensor value with the threshold value.
