读取模拟口数据空气0完全插入水月700左右
void setup() {
// initialize serial communication at 9600 bits per second:
Serial.begin(9600);
}
// the loop routine runs over and over again forever:
void loop() {
// read the input on analog pin 0:
int sensorValue = analogRead(A0);
// print out the value you read:
Serial.println(sensorValue);
delay(1); // delay in between reads for stability
}
void setup() {
// initialize serial communication at 9600 bits per second:
Serial.begin(9600);
}
// the loop routine runs over and over again forever:
void loop() {
// read the input on analog pin 0:
int sensorValue = analogRead(A0);
// print out the value you read:
Serial.println(sensorValue);
delay(1); // delay in between reads for stability
}

int potPin = 4; //设置模拟口A4传感器信号输入端口
int val=0;
void setup()
{
Serial.begin(9600);
}
void loop ()
{
val=analogRead(potPin);//val值从potPin信号口读取
Serial.print("Moisture Sensor Value:");
Serial.println(val);
delay(100);//延时1S
}
int val=0;
void setup()
{
Serial.begin(9600);
}
void loop ()
{
val=analogRead(potPin);//val值从potPin信号口读取
Serial.print("Moisture Sensor Value:");
Serial.println(val);
delay(100);//延时1S
}

这个要看他用的湿度传感器是模拟还是数字的啊。
