We motivate our research and provide a conceptual introduction which illustrates the need to increase or decrease the level of water, by activating 3 different water gates represented by water pumps here. If there is need to increase the level of water, we can do, decrease the level then also we can do by two different sms. As a first step towards a solution, we take user’s prospective for water saving and time management, which can be deployed on the basic mobile handset device. Subsequently, we suggest general system architecture for this mobile based irrigation system application for farmers and discuss related design decision. This design has been implemented as a prototype which we named “SMS Based Canal Pipeline Water Management”.

INTRODUCTION 1.1 This project is about the technique of wireless sensor, which is used to make irrigation system better for a developing country INDIA. Irrigation water management by SMS approach helps irrigators to determine how much water their crop has been used and how long they need to run their pump or drip system for each day using the latest in remote sensing wireless techniques and mobile phone based delivery services. Wireless device has been gaining popularity in decent year. Cellular phone and other wireless device have driven demand for new wireless technology. While traditional wired solutions provide a sense of reliability, convenience has become a large part of consumer’s needs. We now have everything from blackberry units, to Wi-Fi enabled phones. However, a marketing media has played a large role in the consumer’s perceptive a wireless device. The information below is factual, and provides a non-biased evaluation of current wired and wireless technology. The purpose of this study is to review contemporary wireless network protocols and areas that affect the ability of wireless fidelity (Wi-Fi) technology to secure data transmitted over wireless networks. The research approach takes the form of a case study; in collating the methods used by existing protocols in the implementation of wireless Security
