The DHTXX sensors are very popular among the Arduino Tinkerers. They provide an inexpensive and easy way to measure temperature and humidity.
Learn how to publish temperature and humidity readings from a DHT11 or DHT22 sensor via MQTT with the ESP8266 NodeMCU to any platform that supports MQTT or any MQTT client. As an example, we’ll publish sensor readings to Node-RED Dashboard and the ESP8266 will be programmed using Arduino...
Preparing the Arduino IDE There’s an add-on for the Arduino IDE allows you to program the ESP32 using the Arduino IDE and its programming language. Follow one of the next tutorials to prepare your Arduino IDE to work with the ESP32, if you haven’t already. Windowsinstructions – ESP32...

Note that If you’re using a different sensor than the DHT11, you can comment and uncomment the right DEFINE line to use your sensor. // Uncomment one of the lines below for whatever DHT sensor type you're using! #define DHTTYPE DHT11 // DHT 11 ...
