MQ-2 and Flame Sensor combined to make a Fire alarm System

Need Help With My Project

You have a number of issues including:

An unwanted semicolon here:

The wrong number of closing curly brackets in your notifyOnFire() and notifyOnSmoke() functions.

A typo in the word “Interval” in your second timer:

and these two timers are trying to execute at exactly the same time, so they need a small delay between each.

Here’s the amended code:

//Blynk Fire Alarm Notification
#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
BlynkTimer timer;
//Auth Code, Wi-Fi and others.
char auth[] = "XXXX"; //Auth code sent via Email
char ssid[] = "XXXX"; //Wifi name
char pass[] = "XXXX";  //Wifi Password
int flag=0;
int gas_value;
int gas_avalue;


void notifyOnFire() //Flame Sensor Code
{
  int isButtonPressed = digitalRead(D1);
 if (isButtonPressed==1 && flag==0)
 {
    Serial.println("Fire in the House");
    Blynk.notify("Alert : Fire in the House");
    flag=1;
 }
  else if (isButtonPressed==0)
  {
    flag=0;
  }
}

void notifyOnSmoke() //SMOKE Sensor Code
{
  int isButtonPressed = digitalRead(D2);
  if (isButtonPressed==1 && flag==0)
  {
    Serial.println("Alert!!! SMOKE is Detected.");
    Blynk.notify("Alert!!! SMOKE is Detected.");
    flag=1;
  }
  else if (isButtonPressed==0)
  {
    flag=0;
  } 
}


void setup()
{
  Serial.begin(115200);
  Blynk.begin(auth, ssid, pass);
  pinMode(D1,INPUT_PULLUP);
  pinMode (D2,INPUT_PULLUP);
  timer.setInterval(1000L,notifyOnFire);
  delay(100);
  timer.setInterval(1000L,notifyOnSmoke); 
}

void loop()
{
  Blynk.run();
  timer.run();
}
