The system has a distributed wireless network of soil-moisture and temperature sensors. This project focuses on a smart irrigation system which is cost effective. As the technology is growing and changing rapidly, Wireless sensing Network (WSN) helps to upgrade the technology where automation is playing important role in human life. Automation allows us to control various appliances automatically. DC motor based vehicle is designed for irrigation purpose. The objectives of this paper were to control the water supply to each plant automatically depending on values of temperature and soil moisture sensors. Mechanism is done such that soil moisture sensor electrodes are inserted in front of each soil. It also monitors the plant growth using various parameters like height and width.

Introduction In China, water resource is in severe shortage and agricultural water consumption accounts for about 80% of the total water consumption. Because of out-dated agriculture irrigation method, the coefficient of irrigation water for effective utilization is only 0.3-0.4 or so. One important way to improve the utilization rate of irrigation water is to implement precise controlled information on the basis of water crops demand data. In the modern drip irrigation systems, the most significant advantage is that water is supplied near the root zone of the plants drip by drip due to which a large quantity of water is saved. At the present era, the farmers have been using irrigation technique in India through the manual control in which the farmers irrigate the land from time to time. This process sometimes consumes more water. Automatic irrigation scheduling consistently has shown to be valuable in water use efficiency with respect to manual irrigation based on direct soil water measurements. The aim of the implementation is to demonstrate that the automatic irrigation can be used to reduce water use. The implementation is a automated irrigation system that consists of a distributed wireless network of soil moisture and temperature sensor. There are different types of method for irrigating farm field for different types crop field. Basically Indian farmer use these three methods channel system, sprinkler system, drip system. Channel system is a traditional method of irrigation. But a smart irrigation system is a new technology to irrigating farm field automatically. Drip irrigation is one of the methods of irrigation that saves water and fertilizer. In drip irrigation method, water drips slowly to the roots of the plants either onto the soil surface or directly onto the root zone through a network of valves, pipes, tubing and emitters. The process is completed in narrow tubes so that water is given directly to the root of the plant. Drip irrigation is also termed as localized irrigation or micro irrigation. Main purpose of this project is to save the water and to increase the production of crops by monitoring the growth of plants. To substitute the flooding method/manual method of giving water to each plant by irrigation system. To design irrigation by drip that would be economical and efficient as water management has a crucial importance. To maximize utilization of available water. The conventional drip irrigation system is fully controlled and monitored by the farmer. This project presents a fully automated drip irrigation system which is controlled and monitored by using Raspberry Pi. 1.1. Background Irrigation refers to the process of supply of water through artificial means such as pipes, ditches, sprinklers, etc. The irrigation system helps the farmers to have less dependency on rain-water for the purpose of agriculture. The necessity and importance of irrigation is highlighted below in points: 1) Variety of Climate: Indian climate and weather conditions experiences a varied range of climate. There is extreme heat at some places, while the climate remains extremely cold at other places. While there is excessive rainfall at some places, other places experience extreme dryness. So, irrigation is needed in India. 2) Irregular and uncertain monsoon: India is a land of monsoon. But monsoon is irregular and erratic in nature. Sometimes it comes easily and brings heavy rainfall, but sometimes it come late and brings inadequate rainfall. Further, there is irregularity in the distribution of rainfall throughout the year. The irrigation system helps the farmers to have less dependency on rain-water. During the months of inadequate rainfall, the crops are supplied water through irrigation systems. 3) Agriculture based economy: Indian economy is based on agriculture. A large portion of Indian population depends on agriculture. Without irrigation agriculture is not possible in dry areas or during the months of inadequate Paper ID: NOV164836 http://dx.doi.org/10.21275/v5i6.NOV164836 2345
