Rain Detection Sensor Module + สาย Jumper

Rain Sensor Module Arduino Sketch

The sketch below does a couple of things:

1.  It monitors the digital output from the module and makes the decision that it is raining if the digital output goes low.
2. It measures the analog output and provides a moisture level, where 1023 is high and where 0 is very wet.

Copy and paste the sketch below and upload it into your Arduino.

int nRainIn = A1;
int nRainDigitalIn = 2;
int nRainVal;
boolean bIsRaining = false;
String strRaining;


void setup() {
  Serial.begin(9600);
  pinMode(2,INPUT);
}
void loop() {
  nRainVal = analogRead(nRainIn);
  bIsRaining = !(digitalRead(nRainDigitalIn));
  
  if(bIsRaining){
    strRaining = "YES";
  }
  else{
    strRaining = "NO";
  }
  
  Serial.print("Raining?: ");
  Serial.print(strRaining);
  Serial.print("\t Moisture Level: ");
  Serial.println(nRainVal);
  
  delay(200);

}
