The Design of The Smart Card Shower Water Hippo
Abstract: With the rapid development of economy in our country, all walks of life to the demand of water resources is becoming more and more big. Water is a valuable human resources. There is a serious waste of water resources in some bathing places phenomenon. This paper mainly for small and medium-sized bathing places like school factory design a smart card shower water hippo, to improve the bathroom waste water reduction serious problem. Smart card shower water hippo design by using the principle of the single-chip microcomputer AT89C52 as the control chip of the system. When the card into card slot, through the body temperature of the infrared induction, shower water. Using a flow sensor to control water flow. At the same time, billing for card and display on the LCD. When card draw water stopped flowing. Smart card shower water hippo has a safe and reliable, convenient use. Whole design is a combination of flow control, liquid crystal display, infrared detection, radio frequency card billing and other aspects of knowledge.
Key Words: AT89C52; Liquid crystal display; Infrared sensor; Flow sensor

智能卡淋浴节水器的设计 引言
水是人类宝贵的资源，随着社会经济的快速发展，各行各业对水资源的需求量随之增加，同时出现水资源浪费的现象，勤俭节约是中华民族的传统美德，节约用水从我们自身做起，中国现在走的是可持续发展道路，节约用水是我们的责任和义务。
本文针对学校、工厂等中小型淋浴场所设计出一种智能卡淋浴节水器，在以往的淋浴器中有老式淋浴器、脚踏式淋浴器和红外感应淋浴器等，这些淋浴器不能有效的解决浴室水资源浪费的问题，在使用的过程中经常遇到人走淋浴器未关的状况，有容易损坏、使用不方便等缺点。随着淋浴市场的发展，智能卡淋浴节水器逐渐取代这些淋浴器，它是通过感应人体红外线来控制淋浴喷头开关，同时对射频卡计费，使我们树立节约用水的观念，减缓浴室水资源浪费严重的问题。
