Now you know, that how we read the DHT sensor in ESP32 using Arduino IDE. For using the MQTT protocol we will need two more libraries WiFi and pubsubclient. The WiFi library is for connecting the ESP32 with a network. The pubsubclient library is for using the MQTT functionalities in the ESP32. #include .

3 Control ESP32 Actuators over MQTT AskSensors Documentation

MQTT will be used to transport messages between ESP32 and client application. All the messages are JSON encoded.We already know how to connect ESP32 to Access point and MQTT broker from this post. You can check this post by Nuno Santos to know more about parsing JSON messages using ArduinoJson library. ESP32 MQTT LED Control

MQTT Set up MQTT Client to Communicate with Broker Realtek IoT/Wi

To use MQTT with the ESP32 we'll use the Async MQTT Client Library. Installing the Async MQTT Client Library Click here to download the Async MQTT client library. You should have a .zip folder in your Downloads folder Unzip the .zip folder and you should get async-mqtt-client-master folder

In this ESP32 tutorial, we will learn to use ESP32 MQTT as a Publisher and Subscriber using Arduino IDE. There will be one ESP32 MQTT publisher and two subscribers. We will publish DHT11 and DHT22 sensor readings to MQTT with ESP32 and one ESP32 will act as a subscriber and Node-Red Dashboard will also subscribe to the MQTT topics and display.

ESP32 MQTT (Introducción)

ESP-MQTT is an implementation of MQTT protocol client, which is a lightweight publish/subscribe messaging protocol. Now ESP-MQTT supports MQTT v5.0. Features Support MQTT over TCP, SSL with Mbed TLS, MQTT over WebSocket, and MQTT over WebSocket Secure Easy to setup with URI Multiple instances (multiple clients in one application)
