# Display the DHT11 sensor reading on a web server using NodeMCU.

The first thing that we need to do is to setup the circuit. For this project we will using the following components:

**What will you need ?** 

* ESP8266 NodeMCU Dev kit board.
* male-to-male jumper wires 
* DHT11 humidity and temperature sensor 
* 4.7k Ohm resistor
* Breadboard 

#### Setting up the circuit

Setup the circuit so that it looks like the one in the diagram below:

![Circuit for DHT11 sensor and NodeMCU (randomnerdtutorial.com)](https://3073865318-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-Ly3RLHyAwTi7Hml5lZN%2F-LyJRM9h7Me8Df5GQD0V%2F-LyJRnFZaLAFPkuU3TTS%2Fesp8266-dht.png?alt=media\&token=a2f5dd5e-c2f2-4367-95a2-0b9a08c9ebbb)

In this activity, we’re wiring the DHT data pin to GPIO5 (D1), but you can use any other suitable GPIO. Read our [ESP8266 GPIO Reference Guide](https://randomnerdtutorials.com/esp8266-pinout-reference-gpios/) to learn more about the ESP8266 GPIOs.
