If there is an accidental fire near the sensor, the sensor will detect and turn off the current and power supply of the house automatically.

Here I show with my hands the LED lights off. I could have turned it off with fire if I wanted to but a lot of kids are inspired to watch this video of mine.so I have made this project video with my hand.

Source code:

int led = 13;

int pin = 2;

int value = 0;

int pirState = LOW;

void setup() {

  pinMode(led, OUTPUT);

  pinMode(pin, INPUT);

  Serial.begin(9600);

}

void loop() {

  value = digitalRead(pin);

  if (value == HIGH) {

    digitalWrite(led, HIGH);

    if (pirState == LOW) {

      Serial.println("Motion Detected!");

      pirState = HIGH;

    }

  }else{

    digitalWrite(led, LOW);

    if(pirState == HIGH){

      Serial.println("Motion Ended!");

      pirState = LOW;

      }

    }

}
