---------------------------------------------------------------------***--------------------------------------------------------------------present era, the farmers have been using the conventional Abstract- Irrigation Automation is used to Sense Soil Moisture Content and intended to produce an automated irrigation mechanism. The proposed system turns the pump motor ON and OFF or changes it's rpm, on detecting the moisture content of the soil. In the field of farming, utilization of appropriate means of irrigation is significant. The advantage of using this technique is to decrease human intervention and make irrigation more reliable. This automated irrigation brings into show an Arduino board ATmega328 micro-controller, is set to collect the input signal of changeable moisture conditions of the soil via moisture detecting system. Principle of this automation is DTMF based cellular technology which has greater penetration than internet in rural areas. Key Words: Arduino, Irrigation, Soil Moisture Sensor, DTMF, Automated Irrigation Mechanism.
1. INTRODUCTION In the present scenario demand for food is continuously increasing and hence requires rapid improvement in food production technology. Generally a simple and precise method should be used for a country like India, where the economy is mainly based on agriculture. It helps in time saving, removal of human interference in agriculture. Due to uncertainty in the climatic conditions, still an error can occur in adjusting available soil moisture levels and we are not able to make full use of agricultural resources and increase their net profits. The main reason is the lack of rainfall& scarcity of fertile land. Irrigation is the artificial means of supplying water to the soil reservoir. The continuous extraction of water is usually needed in growing the crops. Ground water lever has decreased to a much extent due to which lot of areas have becomes dry and barren but due to the scarcity of land farmers are forced to cultivate the crops in these regions as well. In these areas rainfall is very scarce even in the monsoon season, rainfall arrives very slowly in these regions. Another shortcoming is to protect crops from frost. Very important reason of this is the unplanned use of Irrigation water due to which a significant amount of water is wasted. In irrigation, this technique is very significant. Advantage of this technique is that water is supplied to soil by sensing its moisture content. In this, water is supplied only when the moisture content is below the required level. Due to which a large quantity of water is saved. At the Š 2017, IRJET

irrigation techniques like methods through manual control sprinklers, flood type feeding system (in which farmers irrigate the land at the regular intervals). Water is supplied generally to lower leaves and stem of the plants along with the soil. This process sometimes consumes more water than requires or sometimes the surface becomes saturated, unable to absorb more water and often stays wet, long after irrigation is completed and the area becomes like quagmire. Sometimes the water reaches late due to which crops are destroyed because such condition promotes infections when leaves get dried. Water deficiency can be detrimental to plant’s mold fungi. On the contrary this technique acts before visible wilting occurs. Slowed growth rate, occurs due to the water deficiency. This problem can be solved if we maintain favourable soil condition with the help of controller based irrigation system in which the moisture condition are retained and prevent moisture loss from the plant. This saves requirement of water. Further in country like India cellular technology has much deeper penetration than internet so technology like DTMF offers lots of promises and it's easy interface makes it one of the best options for Indian farmers.
