我做的這個是用yl-69 土壤濕度傳感器檢測濕度然后用adC0832模數轉換然后交給單片機判斷的，仿真里面的可以實現，但是實物焊接出來我把土壤濕度傳感器全部放到水里，lcd1602顯示的當前濕度還是0，請問這個是我程序的問題嗎？
void LCD1602Show()
{
if(state==0)
{
LCD1602Write(0,0x80); LCD1602Write_byte("Humidity:")
LCD1602Write(0,0x80+9);
if(RH>99)LCD1602Write(1,0x30+RH/100%10)；
else LCD1602Write_byte(" ");
LCD1602Write(0,0x80+10);
