摘 要
水作为人们的生命之源，当前对水温的加热，满足当前不同用户对水温的需求，但当前，人们进行水的加热大多数使用热水壶或者水箱进行加热，当人们谁用水壶进行加热时，需要对其进行多次查看，或者在其周围等待，当水加热好之后进行电源关闭，否则会一直进行加热，轻则导致电能浪费，重则水壶烧坏或者发生火灾等问题。为了解决这些问题，此次设计一款智能化的热水器；这款热水器采用STC89C52单片机作为此次设计的主控芯片，采用DS18B20作为此次设计的水温监测模块，采用两个水位监测模块对热水器当前的水位进行实时监测，当监测到水位低于设置的最小值，进行加水，直到水位到达最大值，此外通过光敏电阻对当前的光照强度进行实时监测，监测到当前的光照强度大于设置的最小值，此时采用太阳能对其进行供电，否则采用市电进行供电，当水温和水位处于正常设置范围之内，可以正常进行供水，当监测到水温和水位不在设置的范围之内进行声光报警提醒用户，此外用户可以通过按键设置水温的上下限值和光照最小值，监测的数据通过LCD1602进行显示。

Abstract
Water as the source of life of people, the current of water temperature heating, meet the needs of the different users of water temperature, but at present, most people in the water heating with heating or hot water tank, when people who use the kettle for heating, need to be check for many times, or in the surrounding waiting, when water is heated after power off, Otherwise, it will be heated all the time, which will lead to a waste of power, and the kettle will burn out or have a fire. In order to solve these problems, the design of an intelligent water heater; This water heater uses STC89C52 microcontroller as the main control chip of this design, and DS18B20 as the water temperature monitoring module of this design. Two water level monitoring modules are used to monitor the current water level of the water heater in real time. When the water level is lower than the minimum value, water is added until the water level reaches the maximum value. In addition, the photoresistor is used to monitor the current light intensity in real time. If the current light intensity is detected to be greater than the set minimum value, the solar energy is used for power supply. Otherwise, the mains is used for power supply. When the water temperature and water level are not within the set range, sound and light alarm will be given to remind the user. In addition, the user can set the upper and lower limits of water temperature and the minimum light value by pressing the button, and the monitored data will be displayed through LCD1602.
Keywords: water heater; Water temperature control; Water level monitoring; Light intensity monitoring; Sound and light alarm
