water level sensor ( Powering only during short moments) code

hello again as im a newbie , i need some help adding in to the Sketch 1e] below

const int analogPin = A2;  // if water level sensor module attached to analog pin A0 of Arduino Uno
//const int digitalPin = 7;  // if water level sensor module attached to digital pin 7 of Arduino Uno

int thresholdValue = 200;//you can adjust the threshold value

const int relayPin = 6;//5v relay module attached to digital pin 6 of Arduino Uno
/********************************/
void setup() {
  Serial.begin(9600); // initialize serial communications at 9600 bps
  pinMode(relayPin, OUTPUT);//sets the relayPin as OUTPUT
  digitalWrite(relayPin, HIGH);
}

void loop() {
  int analogValue = analogRead(analogPin);//analog value from soil moisture sensor
 // int digitalValue = digitalRead(digitalPin);//digital value from soil moisture sensor
  Serial.print("Sensor value: ");// send the value from the sensor to serial monitor
  Serial.print(analogValue);// send the value from the sensor to serial monitor
  Serial.print(" ;");
 // Serial.print("Sensor status:");
 // Serial.println(digitalValue);// send the value from the sensor to serial monitor

  if (analogValue >= thresholdValue) {
    Serial.print(" - Water level is HIGH");
    digitalWrite(relayPin, HIGH);
    Serial.println(" - Pump is off");
  }
  else {
    Serial.print(" - Water level is LOW");
    digitalWrite(relayPin, LOW);
    Serial.println(" - Pump is on");
    /*

      if (digitalValue = 1) {
      Serial.println(" - Alarm!!! Water level is high");
      }
      else {
      Serial.println(" - Water level is low");
      }
    */
    }
    delay(200); //sets delay for 200 ms
  }

now how i would power on the sensor only for short moments .Im trying follow the example from sketch 2 .

// Define our pins.
const int soil = A0;
const int power = 12;

// Define our timer.
const int TIMER = 60; // in seconds
const int RESET = TIMER - 1;
const int SENSOR_DELAY = 10; // in milliseconds
int counter;


void setup() {
  pinMode(soil, INPUT);
  pinMode(power, OUTPUT);

  // Start with sensor OFF
  digitalWrite(power, LOW);

  // Setup timer.
  counter = RESET;

  // Setup serial plotter.
  Serial.begin(9600);
}


void loop() {
  // If the counter is at the end of a cycle
  // take a new reading and reset counter.
  if (counter <= 0) {
    // Turn sensor ON and wait a moment.
    digitalWrite(power, HIGH);
    delay(SENSOR_DELAY);

    // Take reading, send to plotter.
    Serial.println(analogRead(soil));

    // Turn sensor OFF again.
    digitalWrite(power, LOW);

    // Start new countdown.
    counter = RESET;
  }

  // If counter isn't at the end yet, pause for
  // the same amount of time as if the sensor
  // had been activated to keep things in sync.
  else {
    delay(SENSOR_DELAY);
  }

  // Decrement counter and delay until next second.
  counter--;
  delay(1000 - SENSOR_DELAY);
}

How would put this together .Thanks

I thought you left power on to the sensors all the time and just checked to see what they are doing.
the Chirp lasts for a growing season on one button battery.

op's capacitive soil sensors....
