Display the DHT11 sensor reading on a web server using NodeMCU.
In this activity we will be connecting the DHT11 humidity and temperature sensor to the NodeMCU development board and displaying them on a web server.
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:
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 to learn more about the ESP8266 GPIOs.
