Abstract: In this part of my research we developed a system which will tackle part of the problem by trying to improve the efficiency of water use in irrigation systems which include the design of decision support software and its integration with an in-field wireless sensor network to implement water pumping irrigation control via Zig bee Technology In our system we have tried to automate the water pumping system to pump the water whenever the prescribed water level or humidity of the soil goes down below prescribed threshold for which water level sensor & Humidity sensor has been taken into account. If the water level is increased beyond the prescribed level during rain or flood, our system automatically lets the extra water and recycles them back to the water tank. Our system also senses the wind speed to predict any storm, other natural calamities and warns the farmer by sending him an SMS using a GSM Technology. For safety purpose we also have fire and temperature sensors to alert the farmer on any kind of such eventualities. The prescribed water level for a crop varies depending on different crops and nature of the soil, so we have developed a user interface to feed the type of soil and crop to automatically set the water level. The farmer is able to control and monitor the field using his PC which is connected to the control system via Zig bee in this situation the web interface provides an excellent platform from which to develop the system. The portability of this technology means that the system could be controlled from anywhere in the world (This phenomena is my complete research).
