WSN based Automated Irrigation Control System

Abstract

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.
