Code For uno

int digitalSensor = 2;

int pumpPin = 8; //relay pin

void setup() {

  pinMode(digitalSensor, INPUT);

  pinMode(pumpPin, OUTPUT);

}

void loop() {

  if(digitalRead(digitalSensor) == HIGH){

    digitalWrite(pumpPin, LOW);

    delay(1000);

  }

  else{

    digitalWrite(pumpPin, HIGH);

  }

  delay(100); // 1hour
