Source Code Deteksi Gas Dengan Arduino

When Hazardous Gas detect then a warning is displayed on LCD and automatic air tight doors are locked to control emissions of hazardous gases.

#include <LiquidCrystal.h>
LiquidCrystal lcd(8, 9, 10, 11, 12, 13);

int Gas_Sensor_Value = 0;
int Gas_sensor = A0;
int Piezo = 3;
int electric_motor_1 = 4 ;
int electric_motor_2 = 5 ;
int electric_motor_3 = 6 ;
int electric_motor_4 = 7 ;


 

void setup() 
{
  lcd.begin(16, 2); // set up the LCD's number of columns and rows:
  pinMode(Gas_sensor, INPUT);
  pinMode(Piezo, OUTPUT);
  pinMode(electric_motor_1, OUTPUT);
  pinMode(electric_motor_2, OUTPUT);
  pinMode(electric_motor_3, OUTPUT);
  pinMode(electric_motor_4, OUTPUT);
}
void loop() 
{
   lcd.clear();
   Gas_Sensor_Value = analogRead(A0);

   if( Gas_Sensor_Value >= 700)
   {
    digitalWrite(Piezo, HIGH);
    digitalWrite(electric_motor_1, HIGH);
    digitalWrite(electric_motor_2, HIGH);
    digitalWrite(electric_motor_3, HIGH);
    digitalWrite(electric_motor_4, HIGH);
    lcd.print("Caution:Gas leak"); // Print a message to the LCD.
     
   delay(1000);
   }
  else
  {
   digitalWrite(Piezo, LOW);
   digitalWrite(electric_motor_1, LOW);
   digitalWrite(electric_motor_2, LOW);
   digitalWrite(electric_motor_3, LOW);
   digitalWrite(electric_motor_4, LOW);
   lcd.print("The environment"); // Print a message to the LCD.
   lcd.setCursor(0,1); 
   lcd.print("is Safe"); 
    delay(1000);
  }
  }
