The weather has been known to be unpredictable. Although, rain is a source of affection for humans and soothes the soul of a person. But sometimes unpleasant things happen if we get no alert. As a result, it may put a lot of things at risk. Therefore the rain sensor was created so that people can get notified when it rains. It is also found in electrical shutters and windows.

void setup() {
//Serial.begin(9600);//enable serial monitor
pinMode(4, OUTPUT);//define LED pin
}
void loop() {
int value = analogRead(A3);//read value
//Serial.print1n("Value : ");
//Serial.println(value);
if (value < 300) {//check condition
digitalWrite(4, HIGH);
//Serial.print1n("Heavy rain LED on ");
} else {
digitalWrite(4, LOW);
}
}
