Here's the code:

char auth[] = BLYNK_AUTH_TOKEN;
char ssid[] = ""; // type your wifi name
char pass[] = ""; // type your wifi password
int smokeA0 = A0;
int data = 0;
int sensorThres = 100;
BlynkTimer timer;
void sendSensor(){

int data = analogRead(smokeA0);
Blynk.virtualWrite(V0, data);
Serial.print("Pin A0: ");
Serial.println(data);
if(data > 300){
//Blynk.email("[e-mail]", "Alert", "Gas Leakage Detected!");
Blynk.logEvent("gas_alert","Gas Leakage Detected");
}
}
void setup(){
pinMode(smokeA0, INPUT);
Serial.begin(115200);
Blynk.begin(auth, ssid, pass);
//dht.begin();
timer.setInterval(2500L, sendSensor);
