Filter Outlet Pressure Based Drip Irrigation System

Drip irrigation is a type of micro-irrigation system where it is probable to save water and nutrients by allowing water to drip slowly to the roots of the plants. Water is incredibly precious to all living beings in addition to plants, trees.The major amount of fresh water is utilized by the agricultural industry for irrigation. In drip irrigation, the water need to be maintained at the constant level which aids in the survival of the plant i.e the water can spread to the roots by going drop by drop.On the other hand, if there is insufficient water, then, the plants may die due to lack of water. Hence there arises a need for the farmer to maintain the water content on the field.The Microcontroller based drip irrigation mechanism, a real time feedback control system is usedfor monitoring and controlling all the activities of drip irrigation system. This system reduces runoff, less watering, saturated soils, avoid irrigating at the wrong time of the day. It improves crop yield and helps in time saving.A filter outlet pressure based drip irrigation system has been implemented in small version and microcontroller is used for ON&OFF of the motor through relay circuit using water flow sensor.
