NODE MCU WITH DHT11 SENSOR

HELLO VIEWERS WELCOME TO THE NEW VIDEO ABOUT HOW TO INTERFACE MODEMCU WITH DHT11 SENSOR AND BLYNK.

CHECK THE LINK BELOW TO THE VIDEO WHICH I POSTED IN MY YOUTUBE CHANNEL

TO ADD NODEMCU BOARD IN ARDUINO IDE:

Instructions:

Start Arduino and open Preferences window.

Enter https://arduino.esp8266.com/stable/package_esp8266com_index.json into Additional Board Manager URLs field. You can add multiple URLs, separating them with commas.

Open Boards Manager from Tools > Board menu and find esp8266 platform.

Select the version you need from a drop-down box.

Click install button.

Don’t forget to select your ESP8266 board from Tools > Board menu after installation

TO ADD ZIP LIBRAY :

VIST TO https://www.arduino.cc/en/guide/libraries#:~:text=In%20the%20Arduino%20IDE%2C%20navigate,ZIP%20Library”.

LIBRARY WHICH WE NEEDED:

DHT11: https://github.com/adafruit/DHT-sensor-library

Adafruit: https://github.com/adafruit/Adafruit_Sensor

Simple timer: https://github.com/jfturcot/SimpleTimer

Spi: https://github.com/PaulStoffregen/SPI

Blynk: https://github.com/blynkkk/blynk-library
