Arduino DHT11 ESP8266 Internet of things Project

Send data (temperature and humidity) to the Thingspeak site with Arduino

Purpose of this project:

Thanks to the Arduino board and the ESP8266 module connected to the Internet of Things (IoT: Internet of Things), it is possible to monitor in real time the temperature and humidity measured by the DTH11 sensor.

To create sensor data recording applications, you can use ThingSpeak which is an API and an open source application for the Internet of Things, allowing you to store and collect data from connected objects.

Necessary components

  • Arduino
  • ESP8266 module
  • DTH11 sensor
  • Connecting wires

Mounting:

To perform the assembly

For ESP8266 module:

  • The RX pin to pin 4 of the Arduino board

  • The TX pin to pin 3 of the Arduino board

  • The GND pin to the GND of the Arduino board

  • The two pins 3V3 and EN to the 5V pin of the power supply module

  • The RST pin to pin 8 of the Arduino board

  • The two pins 3V3 and EN to the 5V pin of the power supply module

For DHT11 sensor:

  • the DATA pin to pin N ° 5 of the Arduino board

  • the VCC pin to the 3.3V pin of the Arduino board

  • the GND pin to the GND pin of the Arduino board
