If yes, then this tutorial is a step-by-step guide for you. We will learn the example of interfacing DHT11 and DHT22 with ESP32 and how to display its values on the web server. DHT11 and DHT22 sensors provide temperature and humidity output on a single wire protocol. We will measure...
In this tutorial, I’ll first go into a little background about humidity, then I’ll explain how the DHT11 measures humidity. After that, I’ll show you how to connect the DHT11 to anArduinoand give you some example code so you can use the DHT11 in your own projects. BONUS: I ma...
Interfacing these sensors with Arduino, ESP8266 and ESP32 is very easy thanks to the Adafruit libraries. You can use our guides to learn how to use these sensors: BMP180: Arduinowith BMP180 Barometric Sensor ESP32 (Arduino IDE)with BMP180 Barometric Sensor BME280: ESP32 (Arduino IDE)with ...
We have another tutorial on the DHT11 for theArduinothat goes into detail on relative humidity and how the DHT11 measures it. So instead of repeating all of that here, check outHow to Set Up the DHT11 Humidity Sensor on an Arduino, then come back for the specifics on setting it up o...
