Agriculture is one of the main sources of income in rural India. Farmers use their lands for cultivating different types of crops and the availability of water for irrigation is one of major factor that influence agriculture productivity. Fluctuates between surplus and almost no water depends entirely on the various monsoons that occur every year. Hence it is imperative to use water resources diligently and effectively. Well water is one of the main sources for irrigation and majority of agriculture fields in India are irrigated using it. Now the problem involved in using well water in about monitoring the flow of water from the well to fields. Huge quantity of well water is wasted due to the lack of availability of technology which measures the flow of water into the fields. In this work, we propose a wireless sensor networks prototype for effective utilization of well water for the irrigation. WSNs provide promising solution in the automation of irrigation process. Floating sensor is used in the prototype to sense the water level in the tank and soil moisture is monitored field condition. The prototypes automate the irrigation process by considering both water levels in tank and moisture requirement in fields. Experiments are carried out using three soil filled trays having different moisture level. Sensor is inserted into the field to measure moisture level. Motor is used to pump the water from water tank to field through water pipes. The system open/close water pipe vales by considering soil moisture in field. Motor is switch on/off by considering waters level in tank. System is experimented using 13 different scenarios and the results show that the proposed prototype is suitable for effective utilization of well water resources based on field conditions. © 2017 Elsevier B.V., All rights reserved.
