Water-Saving Irrigation System Based on Automatic Control by Using GSM Technology

This project proposed an embedded system for automatic control of irrigation. This project has wireless sensor network for real-time sensing and control of an irrigation system. This system provides uniform and required level of water for the agricultural farm and it avoids water wastage. These paper have real time sensing and control of an irrigation system. When the condition of waterin the agricultural farm is abnormal then the system automatically switches ON the motor. When the water level reaches normal level the motor automatically switch OFF. In this project we are interfacing microcontroller through temperature sensor, humiditysensor and also interfacing to GSM through MAX 232.In this we set specified values of temperature, humidity and the conditioned is uniformly monitored by VB.NET. As we know that India is a developing country and and more wired connection. We introduce a new the major part of our GDP growth rate belongs to system which will have wireless connection between agriculture alone. So we can say that agriculture is the server and nodes. We introduce a new design of backbone of India and irrigation is called the lifeline. So, embedded web server making use of GSM network agriculture in India has been the most important priority technology in the paper. Compared to the wired link web in the economic development of country since the server system. This system is characterised by having no independence. Major part of our expenditure is spent on wires between the web server and terminal nodes. These agriculture alone and inspite of that we not getting systems have lower cost and having more flexibility of the required output. In India, there is uneven biological network topology. diversity cause, some part experience droughts while For every node we will use separate GSM trans- some parts flood, so there is always scarcity of water receiver to transmit the details to server nodes. Water available for the irrigation. Farmer in rural area severally irrigation control based on microcontroller and internet of affected by this condition. New technologies coming but things. By internet of things we mean that it has the they are too expensive for the common farmer. The project ability to analyse and distribute data that can be used as offers a cheaper and simpler solution to this problem by information and knowledge. Internet of things improves developing automated microclimate irrigation controllers distribution of world's resources to those who need it the with wireless capability assisted with low cost wireless most. In agricultural farm we use water irrigation is sensor nodes. Like temperature sensor, humidity sensor monitored by using sensor like temperature, humidity. which senses the level of moisture of the soil. The land or Then controller sends sensor to pc using GSM wireless firm is divided into microclimatic regions equipped with technology and updated on the internet using VB.NET. smart specified sensors and integrated wirelessly into automated irrigation controller with wireless networking Functional Blocks Diagram: The functional block
