Abstract
Over population, and the stability of the annual portion of the River Nile for Egypt has led to decrease in the average water per person. Agriculture activity consumes more than 75% of available fresh water so it is important to find new techniques to increase water productivity.
Wireless sensor network WSN is a new technology which paves the way to precision application in many fields. One of these fields is precision irrigation. By precision irrigation it is possible applying water in the right place with right amount at the right time.
Traditional irrigation system depends on regular irrigation which may cause a lot of problem like excessive water irrigation may be cause leaching of nutrients and chemicals to groundwater, in the other hand inefficient water irrigation causes reductions in yield quantity and quality, also inefficient use of fertilizer and other inputs, and decrease water use efficiency.
The target of this study is design a new precision irrigation system to supply the plants with the actual amount of water which the plants need. This study has depended on the use of modern electronic and information system to achieve this target. The main headlines of this study are (1) design wireless sensor based on (IEEE 802.15.4/ZigBee) protocol. This communication protocol gives a new support for low data rate with low power communication. The Arduino Uno board is used as a controller to measure the soil moisture, (2) design a program using c# programming language for collecting the measured values in database designed by Microsoft access
2007, (3) design irrigation system based on the wireless soil moisture sensor, and (4) design a program using c# programming language to control the designed irrigation system. The last stage in this study is applying this system on a real experiment typically on faba bean (Vicia faba). This Iexperiment has been carried out through 126 days, and collecting these data to make a statistical analysis to find the suitable soil moisture range to cultivate the faba bean in Egyptian environment.
