//Micro Electronics

#include <ESP8266WiFi.h>

#include <BlynkSimpleEsp8266.h>

#include <SimpleTimer.h>

#define BLYNK_PRINT Serial    // Comment this out to disable prints and save space

char auth[] = "----------------"; //Enter Authentication code sent by Blynk

 

char ssid[] = "---------"; //Enter WIFI Name

char pass[] = "---------"; //Enter WIFI Password

 

SimpleTimer timer;

 

int mq2 = A0; // smoke sensor is connected with the analog pin A0 

int data = 0; 

void setup() 

{

  Serial.begin(115200);

  Blynk.begin(auth, ssid, pass);

  timer.setInterval(1000L, getSendData);

}

 

void loop() 

{

  timer.run(); // Initiates SimpleTimer

  Blynk.run();

}

 

void getSendData()

{

data = analogRead(mq2); 

  Blynk.virtualWrite(V2, data);

 

  if (data > 700 )

  {

    Blynk.notify("Smoke Detected!"); 

  }
