Code to run smoke sensor

Smoke Sensor

int smokeA0 = A5;
// Your threshold value
int sensorThres = 100;

void setup() {
  pinMode(smokeA0, INPUT);
  pinMode(8, OUTPUT);
  Serial.begin(9600);
}

void loop() {
     Serial.print("");
  int analogSensor = analogRead(smokeA0);

  // Checks if it has reached the threshold value
  if (analogSensor > sensorThres)
  {
    Serial.print("");
    Serial.print("there is fire");
    Serial.print("");
    delay(1000);
    Serial.print(" ");
}
