PV Based Automatic Irrigation System

Abstract

Pakistan is an agricultural country and requires an adequate supply of water for irrigation throughout the year. Water is one of the most precious natural resources and its effectual management is a main concern in various agricultural systems around the world. The major problem is the water accumulation by the wealthy farmers store water for their own fields and allow water to pass to other farmers after receiving the money. Secondly, most of the time water wastage occurs due to over watering, it is because there is very large area in the fields (in acres) that is very difficult for the famers to supervise all the area. Similarly, sometime there is inadequate water supply, which cause the damage of crops or results in lesser yield on some section of the field. This paper presents solution of the mentioned problems and increasing the hold of Indus River Systems Authority (IRSA) on the irrigation mechanism so that the required quantity of water can only be delivered at the specific time for each field (as per requiring output from sensors grounded in field). The presented system consists of implement of the sensors in each corner of the fields, when the sensor value (in voltage) goes to satisfied number it sends notification to IRSA and if the water level goes to danger level, it will automatically close the gate from where water is released. New water system with electrical control advancements can improve water utilization proficiency, compelling water sparing and diminishing the natural affects. The target of the presented system is to dodge wastage of water and enhance efficiency of irrigation by utilizing a PLC based irrigation framework with the assistance of soil dampness sensors. An automatic control system of gates helps to close or open the gates if the water level in soil reaches a critical value. The motivation behind this work was to create a self-administering water supply framework that works on utilization of a solitary model according to which; the water supply follows a pre-supplied timetable along-with the monitoring of the in-field conditions, prompting a sensible sparing in the measure of water supply. It should likewise be dependable and effectively deployable to work under cruel outside conditions without the requirement for oversight or customary checking. The deployed electronic system can be powered through solar energy. The developed mechanism can make farmers capable of fulfilling their irrigation needs besides the PV based generated extra electricity can be shared or sold to neighbors or water and power Development authority (WAPDA).
