Untested. See if you can run your finger through this to see how it works. And if it does what you want.

void printDateTime()
{
  Serial.print(RTC.dayofmonth);
  Serial.print("/");
  Serial.print(RTC.month);
  Serial.print("/");
  Serial.print(RTC.year);
  Serial.print(" ");
  Serial.print(RTC.hours);
  Serial.print(":");
  Serial.print(RTC.minutes);
  Serial.print(":");
  Serial.println(RTC.seconds);
}

int printStatus() {
  static int flag = 0;

  if (Level <= 200) {
    if (flag != -1) {
      printDateTime();
      Serial.println("Signal  OFF ");
    }
    flag = -1;
  }
  else {		// Level > 200
    if (flag != 1) {
      printDateTime();
      Serial.println("Signal  ON ");
    }
    flag = 1;
  }
}

Sry, I don't usually like to hand you a fish. So do take a look. Just one of as many ways to do this as there are programmers, approximately. :expressionless:

It may print more than you want. You could code some hysteresis in there like your home thermostat employs so the A/C not be going on and off alla time.
