Gokit_STM32_V2_1-Test
说明: 1.采用优质土壤传感器做土壤湿度的检测,表面采用镀镍处理,有加宽的感应面积,可以提高导电性能,防止接触土壤容易生锈的问题,延长使用寿命;
2.产品可以宽范围控制土壤的湿度,通过电位器调节控制相应阀值,湿度低于设定值时,DO输出高电平,高于设定值时,DO输出低电平;
3.比较器采用LM393芯片,工作稳定
4.工作电压3.3V-5V
5.设有固定螺栓孔,方便安装
6.PCB尺寸:3.2cm * 1.4m
接线说明(4线制)
1 VCC 外接3.3V-5V
2 GND 外接GND
3 DO 小板数字量输出接口(0和1)
4 AO小板电压模拟量输出
模块使用说明:
1.传感器适用于土壤的湿度检测;
2.模块中蓝色的电位器是用于土壤湿度的阀值调节,顺时针调节,控制的湿度会越大,逆时针越小;
3.数字量输出D0可以与单片机直接相连,通过单片机来检测高低电平,由此来检测土壤湿度;
4小板模拟量输出AO可以和AD模块相连,通过AD转换,可以获得土壤湿度更精确的数值;
使用STM32驱动时,一般使用ADC读取其模拟量输出,以gokit stm32f103c8t6为例;(Detection of Soil Moisture)

stm32-sdPuart
Finally I got it working properly. Reading SDcard was very awesome for me for first time, so I decided to make a library for STM32F4xx devices and post it to my website. It’s basically just communication interface between STM32F4 and FatFS library by Chan. It supports SPI or SDIO communication. Library also supports USB communication, but for that purpose you need USB stack too. USB is available here
