Abstract The developments in the agricultural field are the buzzword in the market. In the field of agriculture, use of proper method of irrigation is important and it is well known that irrigation by drip is very economical and efficient. In the conventional drip irrigation system, the farmer has to keep watch on irrigation timetable, which is different for different crops and it is very difficult. This paper mainly focuses on designing of an accurate & cost effective Global System for Mobile (GSM) Based Automatic Drip Irrigation System using micro-controller. In order to fulfill these objectives we have used relay and solenoid valve along with a 16Ă—2 Liquid Crystal Display (LCD) that can be connected to the microcontroller, which will displays the soil moisture level and ambient temperature. The developed irrigation method removes the need for workmanship for flooding irrigation. Efficient water management plays an important role in the irrigated agricultural cropping systems. Time based control mechanism; volume based control mechanism and priority based mechanism can be designed in one system. Keywords: GSM, Microcontroller, Soil Moisture Sensor, Temperature Sensor, Solenoid Valve _______________________________________________________________________________________________________ I.
INTRODUCTION
In India, where 60-70% economy depends on agriculture, there is a great need to modernize the conventional agricultural practices for the better productivity. Due to unplanned use of water, the ground water level is decreasing day by day. Lack of rain and scarcity of land water also results in decrement in volume of water on earth. In present drip irrigation system water is provided to root zone of plants drop by drop which results in saving of huge amount of water. Agriculture is the backbone of Indian Economy. Without agriculture living is impossible since agriculture produces the main source of food for us. Today the availability of labor for carrying out agricultural activities is less; therefore the automation in agricultural process is needed. In the present era, the farmers have been using irrigation technique in India through the manual control in which the farmers irrigate the land at the regular intervals. This process sometimes consumes more water or sometimes the water reaches late due to which the crops get dried. This problem can be perfectly rectified if we use GSM based automatic drip irrigation system in which the irrigation will take place only when there will be intense requirement of water. Types of Irrigation: Surface irrigation: Surface irrigation is defined as the group of application techniques where water is applied and distributed over the soil surface by gravity. It is by far the most common form of irrigation throughout the world and has been practiced in many areas virtually unchanged for thousands of years. Sprinkler irrigation: In sprinkler irrigation delivery of water is through a pressurized pipe network to the nozzles of sprinkler which spray the water into the air. In other words we can say that, it is a type of artificial rain. Drip irrigation: Drip irrigation, also known as trickle irrigation or micro irrigation or localized irrigation, is an irrigation method which saves water and fertilizer by allowing water to drip slowly to the roots of plants, either onto the soil surface or directly onto the root zone, through a network of valves, pipes, tubing, and emitter. It is done with the help of narrow tubes which delivers water directly to the base of the plant. Need of the Project: Automatic irrigation systems are convenient, especially for those who travel. If installed and programmed properly, automatic irrigation systems can even save your money and help in water conservation. Dead lawn grass and plants need to be replaced, and that can be expensive. But the savings from automatic irrigation systems can go beyond that. Automatic irrigation systems can be programmed to discharge more precise amounts of water in a targeted area, which promotes water conservation. Methodology: There are mainly three methods for Automation: Time-based system: In this system, time is the basis for operation. The basic objective is to prepare a schedule based on crop water requirements. The operation sequence will be set by user as desired.
