circuit diagram

pin connection:

code :

#define BLYNK_PRINT Serial

#include <WiFi.h>

#include <WiFiClient.h>

#include <BlynkSimpleEsp32.h>

#include "DHTesp.h"

#define DHTpin 15 //D15 of ESP32 DevKit

DHTesp dht;

float temperature;

float humidity;

char auth[] = "blynk auth";

char ssid[] = "wifi-name";

char pass[] = "password";

void setup()

{

Serial.begin(115200);

Blynk.begin(auth, ssid, pass);

dht.setup(DHTpin, DHTesp::DHT11);

}

void loop() {

// put your main code here, to run repeatedly:

Blynk.run();

float temperature = dht.getTemperature();

float humidity = dht.getHumidity();

Blynk.virtualWrite(V1, temperature);

Blynk.virtualWrite(V2, humidity);

delay(1500);

}
