Design and Implementation of Automated Irrigation Control System using WSN: An overview

Agriculture plays an important role in Indian economy. It is the biggest water user with the irrigation accounting for 70 percent of global water usage. It is assumed that without improved efficiency of water usage, the consumption of agriculture water can increase by 20 percent by 2050 at global level. In our country rainfall controls the agriculture; but the rainfall is non-uniform and irregular. This creates hassle in irrigation which badly affects the agriculture produce. This paper reviews different smart irrigation methods to achieve the efficiency in water use, higher production levels, low cost, decreased manpower requirements, higher reliability in water supply and certainly higher profits to farmers. The smart irrigation system should be cost effective so that the farmers can use it in the farm field

WSN based Automated Irrigation Control System

The main aim of this work is to provide an automated irrigation system for the farmer on the basis of wireless sensor network. The challenge is to develop such an irrigation control system that makes efficient usage of water and also must be cost effective. To calculate plant’s water requirement, it is important to measure different parameters. This system continuously monitors the parameters- temperature, humidity, and moisture of soil to which crops are susceptiveAn algorithm was developed with threshold values of soil moisture to be maintained continuously. System starts or stops irrigation based on moisture content of the soil. The tests were conducted on three crops- green chili, marigold and tomato. With the help of this system, water supply was reduced by 20- 30%, while crop yield was found to be slightly increased
