Week 4 (FYP 2)

Write the programming code

This is my programming code for The Development of Gas Leakage Detector for Home Appliance. But this is not already full programming code because I'm not testing yet with node mcu and there is a little bit correction in this programming code. Later I will update if the programming code was successful and does not have a correction. 

int red_led=12;

int green_led=11;

int buzz=13;

int gas_value;

int gas_avalue;

int sensorThres=400;

void setup()

{

pinMode(red_led,OUTPUT);

pinMode(buzz,OUTPUT);

pinMode(green_led,OUTPUT);

pinMode(A1,INPUT);

Serial.begin(9600);

}

void loop()

{

gas_avalue=analogRead(A0);

if (A0 > sensorThres)

{

digitalWrite(red_led, HIGH);

digitalWrite(green_led, LOW);

digitalWrite( buzz, HIGH);

Serial.println(“DANGER!!!!”);

Serial.println(gas_avalue);

}

else

{

digitalWrite(red_led, LOW);

digitalWrite(green_led, HIGH);

digitalWrite( buzz, LOW);

Serial.println(“NO LEAKAGE”);

Serial.println(gas_avalue);

}

delay(100);

}
