Design and Implementation of an Automatic Soil Moisture Sensor Irrigation System

As India is an agriculture oriented country and the rate at which water resources are depleting is a dangerous threat hence there is a need of smart and efficient way of irrigation. At present most of the farmers have been using irrigation techniques through the manual control in which the farmers irrigate the land at the regular intervals. This process sometimes consumes more water or sometimes the water reaches late due to which the crops get dried. Over-irrigation can increase energy consumption and water cost as well as leaching of fertilizers below the root zone, erosion, and transport of soil and chemical particles to the drainage ditches. Irrigators who monitor soil moisture levels inthe field greatly increase their ability to conserve water and energy, optimize crop yields, and avoid soil erosion and water pollution.This paper described to provide an automatic irrigation systemusing AT89S51 microcontroller,thereby saving time, money & power of the farmer. With thisautomated technology of irrigation the human intervention can be minimized. This system is best suited for places where water is scarce and has to be used in limited quantity.
