设计了一种基于AVR单片机的盆栽自动浇水系统。该系统以 ATmega 16 L 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ATmega 16 L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。

The article is about the design of an automatically watering system for pot plant .The design of the system is related to the AVR microcontroller , which takes ATmega 16 L as the main control unit .The system memorizes the humidi-ty base thresholds into the built-in EEPROM memory system , then adjusts the humidity level to different plant growing environment by changing the level of acceptable water amount .Besides , for watering the plants at a right amount , the system automatically adjusts the humidity thresholds by combining the humidity base thresholds and the data gathering by the temperature sensor , and then converts the current humidity by the built-in A/D converter .Furthermore , the system can adjust the time and date accurately by the internal timer , and achieves the purposes of checking and watering at regu lar time .The tests demonstrate that the system can automatically control the pot plant irrigation amount and time ac-cording to the temperature and humidity , and effectively work for the pot plant irrigation automated management .
