طراحي و پیاده سازی يك سيستم آبیاری هوشمند بر اساس
شبکه های سنسوری
متوسط میزان بارندگی در کشور ایران یک سوم میانگین جهانی است و از این بابت جزو مناطق خشک جهان محسوب می گردد. لذا صرفه جویی در مصرف آب اهمیت فوق العاده ای دارد. با توجه به اینکه 95% از آب استحصالی در بخش کشاورزی مصرف می شود و 5% باقیمانده در بخش صنعت و خانگی به مصرف می رسدبه همین دلیل عمده تمرکز باید بر صرفه جویی در بخش کشاورزی باشد. از این بابت متخصصان این بخش جایگزینی روشهای نوین آبیاری به ویژه آبیاری تحت فشار را با روشهای قدیمی و سنتی پیشنهاد می کنند و به تدریج این روش فراگیر می شود.مساله ای که باقی می ماند میزان آبی است که باید به گیاه داده شود. آبیاری کمتر از نیاز گیاه سبب افت محصول و ایجاد خسارت شده و آبیاری بیش از حد نیز سبب اتلاف آب و افزایش هزینه ها خواهد گشت.
این کار فعلا بطور تجربی و یا بر اساس جداولی که بصورت تجربی نیاز آبی گیاه را مشخص می کند انجام می گردد. نیاز آبی هر گیاه بر حسب نوع آن و دمای محیط مشخص می شود. اما مشکلی که وجود دارد این است که در اینگونه جداول تغییرات رطوبت و یا دمای محیط لحاظ نگردیده است.
در این پایان نامه روشی بهتر و کاملتر برای اینکار معرفی می گردد که بر مبنای سنجش رطوبت پایه گذاری شده است. در این روش از آبیاری هوشمند، یک سنسور رطوبت سنج در پای گیاه و در درون خاک نصب می گردد و در صورتی که رطوبت خاک از حد مشخصی کمتر شد نیاز به آبیاری مجدد اعلام می گردد. لیکن با توجه به اینکه رطوبت سنج در فاصله های مختلفی از ریشه نصب شده و یا عمق آن و یا حتی نوع خاک در قسمتهای مختلف مزرعه متفاوت می باشد پاسخها متفاوت خواهد بود.از این جهت از چندین سنسور و در چند جای متفاوت استفاده میشود. اطلاعات این سنسور ها از طریق فرستنده های زیگبی به یک واحد مرکزی انتقال پیدا می کنند و در آنجا بر اساس میانگین گیری بر آبیاری مجدد تصمیم گیری خواهد شد.
کلمات کلیدی:آبیاری تحت فشار، رطوبت، آبیاری هوشمند، میانگین گیری، فرستنده های زیگبی

A third-party online payment processor like PayPal, the Skrill e-wallet lets you transfer funds in and out of several US online casinos. It’s just as easy to use, and it offers fast online casino transactions and few to no fees. According to a CNBC report of September 2015, some US-facing online casinos started offering PayPal as a payment option after nearly 10 years of staying away from the US market. The online payment processor started pre-approving US online casinos very quietly and hardly released any information about any changes to its policies. PayPal is a favorite payment method for both players and casinos. As such, it’s available at most US online casinos (aka PayPal Casinos USA). Look at the toplist to pick from the best PayPal sites to play at.
