随着生活质量的提高，越来越多的人喜欢在家中养花，但经常因不能及时照顾花的生长环境而导致花枯萎。为改善这种情况本系统提出了一种基于51单片机的智能浇花系统，该系统是以51单片机为主控制器，通过DS1302时钟模块设定在固定的时间进行浇水，浇水的时间为60秒；同时使用温度传感器DS18B20和湿度传感器对土壤的温度和湿度进行检测，当检测到的环境状况是属于土壤缺水的情况，则主控制器会打开水泵开关开始浇水，当不在是缺水的情况时则停止浇水。经过后期的多次测试，该系统可以成功的实现预期的设计目标。(With the improvement of the quality of life, more and more people like to grow flowers at home, but often fail to take care of the growing environment of flowers in time to cause the flowers to wilt. In order to improve this system, an intelligent watering system based on 51 single-chip microcomputer is proposed. The system is based on 51 single-chip microcomputer as the main controller. The system is set at a fixed time through the DS1302 clock module to water for 60 seconds. The temperature and humidity of the soil is also used by the temperature sensor DS18B20 and the humidity sensor. The main controller opens the water pump switch to water and stops watering when the water is not in the condition of water shortage. After many tests, the system can achieve the desired design goals successfully.)
