摘要在当今忙碌的社会生活中，养护绿植越来越成为人们缓解生活压力的一种方式。绿植既能让人们获得栽培的愉悦又能净化生活空气，但如不能及时为其补水绿植就会干枯而死。随着当今微电子科技日趋成熟，单片机被广泛应用于生活中，单片机已经能够解决这一问题。本次设计就是采用单片机实现的智能绿植养护系统。本次智能绿植养护系统设计主要采用STM32单片机作为核心元件，通过不断检测土壤湿度传感器传送的信号判断绿植是否需要浇水。如湿度过低则单片机控制水泵进行浇水，直到湿度达到标准范围才停止浇水。本系统还配有LCD1602液晶显示屏用来显示土壤当前的实时湿度。除此以外，用户还可根据绿植的种类和需要通过按键模块自行控制补水量，实现精确补水。本次毕业设计对于居家绿植养护甚至园林灌溉都有一定的参考价值。关键词：STM32单片机；土壤湿度传感器；按键控制；绿植养护 Abstract In todays busy social life, the maintenance of green plants has increasingly become a way for people to relieve the pressure of life. Green plants can not only make people get the pleasure of cultivation but also purify the living air. With todays mature microelectronics technology, SCM is widely used in life, SCM has been able to solve this problem. This design is the use of single-chip intelligent plant maintenance system.The design of this intelligent green plant maintenance system mainly USES STM32 single chip microcomputer as the core component, to judge whether the green plant needs watering or not by constantly detecting the signal transmitted by the soil moisture sensor. If the humidity is too low, the single-chip microcomputer controls the water pump for watering until the humidity reaches the standard range before stopping watering. The system is also equipped with LCD1602 LCD to display the current real-time moisture of soil. In addition, users can control the amount of water replenishment by themselves according to the types of plants and the needs of the button module to achieve accurate water replenishment. This graduation project has certain reference value for the home green plant maintenance and even garden irrigation.
