NodeMCU ESP8266 Monitoring DHT11/DHT22 Temperature and Humidity with Local Web Server

In this project, we will create a standalone web server using a NodeMCU ESP8266 that displays the temperature and humidity with a DHT11 or DHT22 sensor using the Arduino IDE. Actually, the webserver we will build can be easily accessed with any device that features a browser on your local network. NodeMCU ESP8266 Monitoring DHT11/DHT22 Temperature and Humidity with Local Web Server. Throughout this tutorial we’ll show how we build web servers:

 

Web Server: Asynchronous web server which will updates the temperature and humidity automatically. We don’t need to refresh the webpage to update the data. Actually, we have used custom CSS to style the webpage.
