【摘要】：设计了一种基于AVR单片机的盆栽自动浇水系统。该系统以ATmega16L单片机为主控芯片,利用单片机自带的EEPROM存储器保存浇水的湿度基准阈值,通过按键可调整湿度基准阈值,以适应不同的花卉盆栽生长需要和地域的气候条件;根据温度传感器采集的温度数据自动调整湿度阈值,以保证盆栽在温度变化时的浇水量适中;使用单片机内置的A/D转换器把湿度传感器采集的湿度模拟量转换成当前湿度值,利用单片机内部定时器进行中断计时,以准确调整系统的日期和时间,达到了定时检测浇水及自动调节浇水量的目的。该系统充分利用了ATmega16L单片机资源,简化了系统设计,具有硬件结构简单、成本低、工作稳定等优点。实际测试表明:该系统能根据温湿度对盆栽浇水进行自动控制,实现盆栽浇水无人值守功能,满足了多种条件下盆栽浇水的需求,可有效地用于盆栽浇水的自动化管理。
[Abstract]:A pot plant automatic watering system based on AVR microcontroller is designed, in which ATmega16L microcontroller is used as the main control chip. The humidity reference threshold of watering can be saved by the EEPROM memory provided by single chip microcomputer, and the humidity reference threshold can be adjusted by keystrokes to meet the needs of different potted plants and the climatic conditions in different regions. According to the temperature data collected by the temperature sensor, the humidity threshold was automatically adjusted to ensure that the watering quantity of the potted plant was moderate when the temperature changed. The analog humidity collected by humidity sensor is converted into the current humidity value by using the built-in A / D converter of the single chip microcomputer, and the interrupt timing is carried out by using the internal timer of the single chip microcomputer to accurately adjust the date and time of the system. The system makes full use of ATmega16L single chip computer resources, simplifies the system design, has simple hardware structure and low cost. The practical test shows that the system can automatically control pot watering according to temperature and humidity, realize the function of unattended potted watering, and meet the needs of pot watering under various conditions. It can be used effectively in the automatic management of pot watering.
