How to configure Blynk with the ESP32/ESP8266 - Arduino Tutorial

In this tutorial I will show you how to configure an ESP32 device within the Arduino IDE and connect it to the Blynk mobile App tp monitor/interact with a variety of projects, in this example a temperature and humidity monitor for a mini greenhouse.

The ESP32 device used in this tutorial can be purchased here:

You'll also need an DHT11 temperature and humidity sensor:

The Arduino code for this tutorial is available here:

Christ, why cant every tutorial be as concise as this one. Thanks.

you gained a sub man true and brilliant work great help i just got my first esp32 this helped me no actually made me able to setup blynk on it

[GameDesignverse]

Thanks man. Finally I'm able to do something with the esp32
thanks a lot.

How can we use BlynkSimpleEsp8266.h library for Esp32 board.

[codexrat]

I wanted to ask one question,
The virtual pins you used in the app, how is the blynk app able to auto connect to the variables that hold the actual data of temperature and humidity in the esp board?
Maybe some code you edited in the IDE and didnt mention?

Can i still follow the steps one by one but with Esp8266??

[scottmestel]

Perhaps you meant to say "natively supported" ? 0:53

[hrishikeshgarud]

is there any way to download the sensor data from blynk?

[kenwayjohn]

hello sir, can u make tutorial with esp32 with pH sensor and monitor using blynk?
oh yeah! one more, esp32 and TTGO esp32(built in LoRa) can use the same coding?

[tothbalazs]

hy, i tried this and work well, than i changed the input pin from 13 to 34. Have you any idea why doesn't work than?

Hello how are you.
doit esp32 devkit v1 no longer reads in wifi phone
Could you please help me?

[kenwayjohn]

hello, sir need help with Blynk app here, I connect my two sensors which is temperature and ph sensor to esp32 dev board. the problem is my blynk app keeps telling me the value is 1 until 999 and so on for both sensor. but when i click on serial monitor at arduino ide the reading is ok. what is the problem? is it because of coding? please help me sir because i need to submit my work ASAP.


i am using
Blynk.virtualWrite(V5, millis() / 1000); for temp
Blynk.virtualWrite(V56 millis() / 1000); for ph
