5、活、工业生产、农业生产、科技领域等各方面都不可或缺。然而淡水资源的有限与人类对水的日益需求增加的这一矛盾日趋严重。因此，在社会矛盾突出的现代，我们应大力提倡节约用水，走可持续发展道路。为了响应国家的号召，建设“资源节约型”社会，结合所学的专业知识，为此设计一个自动水龙头控制电路。针对节约用水问题，特开发一种既能节水，又操作简单方便，实用性强的自动水龙头方案。设计自动供水电路不但可以节约有限的水资源，还可以降低公司内部的成本，达到资源节约的目的。本设计介绍了红外发射电路、红外接收电路、滤波整流电路、灵敏度调节电路、以及电

6、磁阀控制电路，从而达到控制水龙头的自动开启和关闭的目的。由于所学知识有限，在设计过程中有不恰当之处，望老师予以指教。【关键词】：资源节约可持续发展红外装置滤波整流灵敏调节电磁阀控制自动关闭Wateristhesourceoflife,humanbeingsforthedemandofwaterresourcesisincreasing,butfreshwaterresourceinourdailylife,industrialproduction,agriculturalproduction,scienceandtec
