Optimum utilization of water for irrigation is serious need of the hour. This paper proposes a self-regulated approach in the irrigation industry. This approach uses water level sensors at storage tanks and moisture sensors at the field for conservation of water. Using integrated ICs and latest technology this system is made completely free from any human intervenience. As mobile phones are an integral part of human life, GSM module was used to notify the farmer about every update.

INTRODUCTION Agriculture is practiced in India since human civilization a long ago at present 61.5% of Workforce in India is directly working in the agriculture being broadest economic sector. India produces 80% of agricultural produce basically sugarcane and numerous vegetables for cultivation of such cash crops huge quantity of water is required. The need for the water is fulfilled from canals from rivers, groundwater well-based systems, tanks and other rainwater harvesting projects out of which groundwater system is the largest, therefore optimum utilization of groundwater for irrigation is serious call of hours. It is hence necessary to understand the importance of plant and soil system for optimum utilization of water by use of latest technology. Traditionally water was lifted from the groundwater system by humans using animal power and then used for irrigation supplied to the filed by way of flood irrigation. This method required human interference at the initial stage of lifting the water from ground level and to irrigate the fields. Most of the time, fields were over flooded with more water than what is required to the plants leading to wastage of water and may cause soil erosion. Nowadays drip irrigation is used for supply of water from storage tanks through pipes, valves etc. and allow it to drip slowly at the root of the plant which considerably reduces the wastage of water but arrest of total wastage of water cannot be ruled out. Valves which come in various types are used to control the flow of water manually or automatically but in either case a close inspection on the water tanks is needed. If one holds less knowledge about drip irrigation then surface drip irrigation can cause a problem by supplying less water than required by the plants or vice versa. We like to introduce a system, which is fully automated from the initial stages of pumping water automatically into the tanks and supply to the fields in consonance with the water required by the plants. The whole system is divided into three parts water level indicators in the water tank, automatic soil irrigation system and the notification system. The system does not require human interference at all on the contrary the farmer gets an alert on their cell phone through GSM module. The system is introduced with microcontroller that acts as the brain of the system. II. PROPOSED SYSTEM The system is divided into three parts. Firstly, every user has to register his valid phone number into the system; this is the phone number where the user receives notification in the form of short message service (SMS). Two water level indicators are used to ensure that the tank is never empty or over flooded. This two water level indicators are installed in water tank, of which one indicate water tank is empty and the second indicates tank is full. The third arm of the system is the automatic irrigation system. Which makes sure that the plants are only irrigated when the moister contain of the soil reduces. Water Tank System Water storage tanks are primarily used for providing water for irrigation in farming. This storage tanks require manual monitoring and controlling process to prevent overflowing of water leading to wastage of water. Using microcontroller, the water level controller circuit is able to monitor the water level and carefully pump the water from ground water reservoirs using motors. Micro- controller is programmed to sense the water level and turn on/off the valve that fills water in the tank. Whenever the water level is below the minimum level the lower water indicator sense it and sends signal to microcontroller. The microcontroller turns the relay
