摘要 中国水资源严重缺乏,而农业用水又占了总用水量的大部分,根据土壤湿度信息来控制农业灌溉对农业节水具有重要意义。本文基于STM32F103CRT6单片机设计了土壤湿度采集及控制装置,利用TDR-3型土壤湿度传感器的相关物理特性和STM32RCT6单片机的控制功能实现土壤湿度的检测及自动灌溉。该装置包括单片机微控制器模块、土壤湿度传感器模块、液晶显示模块、按键模块、串口模块、水肥机继电器模块和电源模块,可实现自动测量土壤湿度并在液晶上显示,并通过键盘设定适宜作物生长的土壤湿度范围:当土壤湿度小于下限值时,启动水肥机增加土壤湿度;当土壤湿度大于上限值时,水肥机停止工作,实现了对农作物的自动节水灌溉。 China is seriously short of water resources,and agricultural water accounts for most of the total water consumption.Therefore,soil moisture collection and control is of great significance to save agricultural water,and that is the basis of realizing agricultural digitalization.We designed a soil moisture acquisition and control device based on STM32F103CRT6 microcontroller,which used the related physical characteristics of TDR-3 soil moisture sensor,control function of STM32RCT6 microcontroller to realize the detection of soil moisture and automatic control of watering.The device,which included micro controller module,the soil humidity sensor,liquid crystal display module,keyboard module,solenoid valve module,power module,and serial port module,can automatically measure the soil moisture and displayed on the LCD and set up start pump humidity lower threshold through the keyboard.When the device detects the humidity is less than the threshold,start the pump work;when the humidity is greater than the upper limit that also can be set,the pressure pump stops working,so as to achieve automatic control of watering.
