基于Arduino单片机的家庭绿植自动浇水系统
Automatic Watering System for Home Green Plant Based on Arduino Microcontroller

利用Arduino单片机设计了一种绿植自动浇水系统，主要包括主控模块、LCD显示模块、按键调控模块、湿度检测模块、水泵模块及WI-FI模块，使整个系统加入物联网实现全自动化。该系统可以通过对土壤温湿度的检测来判断绿植的生长环境的现状，即缺水还是除湿。且用户可通过手动调节土壤湿度的阈值范围，LCD显示屏显示当前土壤温湿度等信息。当土壤湿度低于设定的阈值时，启动水泵进行抽水浇水，当浇水后的阈值在设定的湿度范围内时，停止浇水。WI-FI模块的加入使整个系统与物联网相连接，方便用户在手机端监控和操作。
An automatic watering system for green plants is designed by using Arduino single chip microcomputer. It mainly includes main control module, LCD display module, key control module, humidity detection module, water pump module and WI-FI module, which makes the whole system join the Internet of Things to realize full automation. The system can judge the status of the growing environment of green plants through the detection of soil temperature and humidity, that is, water shortage or dehumidification. And the user can manually adjust the threshold range of soil moisture, LCD display screen displays the current soil temperature and humidity information. When the soil moisture is lower than the set threshold, the pump is started to pump water, and when the threshold after watering is within the set humidity range, the watering is stopped. The addition of the WI-FI module tries to connect the whole system with the Internet of Things, which is convenient for users to monitor and operate on the mobile phone.
