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
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 to learn more about the ESP8266 GPIOs.
