IOT Weatherstation Combining codes

Hello

Im pretty new at this but i was trying to build and code a weaterstation with Blynk. I have an Weimos D1 R1 with a DHT 22 Sensor with a MQ-135 Gas Sensor. Now i want to add a BMP 280 pressure sensor. I got a working code for my DHT222 and MQ and on another board for my BMP. How can i combine the two? Both codes are down here:

#define BLYNK_TEMPLATE_ID "e"
#define BLYNK_DEVICE_NAME "e"
#define BLYNK_AUTH_TOKEN "e"

#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
 

#include <DHT.h>

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;

#define DHTPIN D3          // Mention the digital pin where you connected 
#define DHTTYPE DHT11     // DHT 11  
#define DHTTYPE DHT22   // DHT 22  (AM2302), AM2321
//#define DHTTYPE DHT21   // DHT 21 (AM2301)

DHT dht(DHTPIN, DHTTYPE);
BlynkTimer timer;

void sendSensor(){
  float h = dht.readHumidity();
  float t = dht.readTemperature(); // or dht.readTemperature(true) for Fahrenheit
  if (isnan(h) || isnan(t)) {
    Serial.println("Failed to read from DHT sensor!");
    return;
 
  
  }

  Serial.println(t);
  Blynk.virtualWrite(V1, h);
  Blynk.virtualWrite(V0, t);
    Serial.print("Temperature : ");
    Serial.print(t);
    Serial.print("    Humidity : ");
    Serial.println(h);


  if(t > 30){
   // Blynk.email("", "Alert", "Temperature over 28C!");
    Blynk.logEvent("temp_alert","Temp above 30 degree");
  }
{
 int data = analogRead(smokeA0);
 Blynk.virtualWrite(V2, data);
  Serial.print("Pin A0: ");
  Serial.println(data); 
}
}

void setup(){
  pinMode(smokeA0, INPUT);
  Serial.begin(115200);
  Blynk.begin(auth, ssid, pass);
  dht.begin();
  timer.setInterval(2500L, sendSensor);

}

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

And the BMP 280

#define BLYNK_TEMPLATE_ID "e"
#define BLYNK_DEVICE_NAME "BMP280"
#define BLYNK_AUTH_TOKEN ""
#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <Wire.h>
#include <SPI.h>
#include <Adafruit_BMP280.h>


char auth[] = BLYNK_AUTH_TOKEN;

char ssid[] = "";  // type your wifi name
char pass[] = "";  // type your wifi password


#define BMP_SCK  (13)
#define BMP_MISO (12)
#define BMP_MOSI (11)
#define BMP_CS   (10)

Adafruit_BMP280 bmp; // I2C
//Adafruit_BMP280 bmp(BMP_CS); // hardware SPI
//Adafruit_BMP280 bmp(BMP_CS, BMP_MOSI, BMP_MISO,  BMP_SCK);

BlynkTimer timer;

void sendSensor()
{
    int temp =bmp.readTemperature();
    float pressure= bmp.readPressure();
    float altitude=bmp.readAltitude(1017);
    Serial.print(F("Temperature = "));
    Serial.print(bmp.readTemperature());
    Serial.println(" *C");

    Serial.print(F("Pressure = "));
    Serial.print(bmp.readPressure());
    Serial.println(" Pa");

    Serial.print(F("Approx altitude = "));
    Serial.print(bmp.readAltitude(1017)); /* Adjusted to local forecast! */
    Serial.println(" m");                    //If you don't know it, modify it until you get your current altitude
    Serial.println();
    Blynk.virtualWrite(V3, temp);
    Blynk.virtualWrite(V4, pressure);
    Blynk.virtualWrite(V5, altitude);                                  //The "1019.66" is the pressure(hPa) at sea level in day in your region
    delay(2000);
}

void setup() {
  Blynk.begin(auth, ssid, pass);
  timer.setInterval(100L, sendSensor);
  Serial.begin(115200);
  while ( !Serial ) delay(100);   // wait for native usb
  Serial.println(F("BMP280 test"));
  unsigned status;
  //status = bmp.begin(BMP280_ADDRESS_ALT, BMP280_CHIPID);
  status = bmp.begin(0x76);
  if (!status) {
    Serial.println(F("Could not find a valid BMP280 sensor, check wiring or "
                      "try a different address!"));
    Serial.print("SensorID was: 0x"); Serial.println(bmp.sensorID(),16);
    Serial.print("        ID of 0xFF probably means a bad address, a BMP 180 or BMP 085\n");
    Serial.print("   ID of 0x56-0x58 represents a BMP 280,\n");
    Serial.print("        ID of 0x60 represents a BME 280.\n");
    Serial.print("        ID of 0x61 represents a BME 680.\n");
    while (1) delay(10);
  }

  /* Default settings from datasheet. */
  bmp.setSampling(Adafruit_BMP280::MODE_NORMAL,     /* Operating Mode. */
                  Adafruit_BMP280::SAMPLING_X2,     /* Temp. oversampling */
                  Adafruit_BMP280::SAMPLING_X16,    /* Pressure oversampling */
                  Adafruit_BMP280::FILTER_X16,      /* Filtering. */
                  Adafruit_BMP280::STANDBY_MS_500); /* Standby time. */
}


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

There are plenty of explanations how to merge codes; e.g. Merging Code

Your topic has been moved to a more suitable location on the forum as this has nothing to do with Avrdude, stk500 or Bootloader.
