Application of routine

Will water vapor sensor according to the program access the Arduino UNO controller, observing testing different humidity value, the measured value of the feedback.

sample code

void setup()
{
    Serial.begin(9600);     
}
void loop()
{
    int val;
    val=analogRead(0);      
    Serial.print("Moisture is ");
    Serial.println(val,DEC); 
    delay(100);
}

Application effect

This program is when you detect the different degree of humidity, the measured value of the feedback back at this time. As shown in the figure below, the temperature sensor test to the boiling water, the value of feedback.
