PAGE PAGE III 内容摘要 ￡ 湿度对植物的生长有着非常大的影响，本文通过用STC89C52单片机来设计出一种智能浇花系统，此系统能够利用YL-100传感器对土壤环境的湿度变化进行实时检测，对采集到的湿度信号进行处理并通过LCD1602液晶显示器显示出来。该智能浇花系统能适用于很多的使用场景，例如居家种植、温室培养甚至是大范围的大棚种植，还可应用于科学研究实验室中。本文清晰的列出了该系统的硬件系统设计和软件系统设计，介绍了本系统的组成及工作原理，最后给出系统的实物展示。此系统能实时自动检测土壤湿度，能根据植物对水分的需求量进行合理的浇水，既能保证植物的生长又能节约珍贵的水资源。实践证明该智能浇花系统具有测量精度高、通用性强等特点，具有一定的实用价值。 关键词：STC89C52单片机；APP；YL-100土壤湿度传感器；实时自动检测 Abstract Humidity has a great influence on the growth of plants. In this paper, an intelligent watering system is designed by using the STC89C52 single-chip microcomputer. This system can use the YL-100 sensor to detect the humidity change of the soil environment in real time, and collect the collected humidity signals. Processed and displayed through the LCD1602 liquid crystal display. The intelligent watering system can be applied to many usage scenarios, such as home planting, greenhouse cultivation and even large-scale greenhouse cultivation, and can also be used in scientific research laboratories. This article clearly lists the hardware system design and software system design of the system, introduces the composition and working principle of the system, and finally gives a physical display of the system. This system can automatically detect the soil moisture in real time, and can reasonably water the plants according to the water demand of the plants, which can not only ensure the growth of plants but also save precious water resources. Practice has proved that this intelligent watering system has the characteristics of high measurement accuracy and strong versatility, and has certain practical value.
