六個問題的答案時范圍基于Arduino的灌溉工程

　　調查項目涉及發現許多經常相互競爭的要求之間的微妙平衡。本文在多系列的第一部分，概述的范圍的水利工程，因為它涉及到提問和回答同一類型的問題需要范圍幾乎任何項目采用的傳感器和執行器它的環境相互作用。

　　There are six main questions that must be answered for any such project：

　　What are the project specific issues and constraints， including fault tolerance？

　　Which processor platforms will satisfy the project requirements？

　　What types of sensors should be used？

　　What types of actuators are appropriate？

　　What communication capabilities are necessary？

　　What are the power management needs？

　　Irrigation is the artificial delivery of water to an area， usually to grow plants. How to create efficient watering systems has challenged mankind since we sowed our first seeds. Agriculture irrigation projects must maximize the benefit they extract from the water that they use because they compete with industry and urban users for scarce fresh-water resources， especially during periods of drought. Fortunately， the opportunity to improve the efficiency of watering systems continues to expand as technology advances.
