Move the Adafruit_sensor folder to your Arduino IDE installation libraries folderįollow the next steps to install the ESPAsyncWebServer library:.Rename your folder from Adafruit_sensor-master to Adafruit_sensor.zip folder and you should get Adafruit_sensor-master folder Click here to download the Adafruit Unified Sensor library.Follow the next steps to install the library. You also need to install the Adafruit Unified Sensor Driver library to work with the DHT sensor. Installing the Adafruit Unified Sensor Driver Move the DHT_sensor folder to your Arduino IDE installation libraries folder.Rename your folder from DHT-sensor-library-master to DHT_sensor.zip folder and you should get DHT-sensor-library-master folder Click here to download the DHT Sensor library.To read from the DHT sensor using Arduino IDE, you need to install the DHT sensor library. ESPAsyncWebServer and Async TCP libraries to build the asynchronous web server.įollow the next instructions to install those libraries:.The DHT and the Adafruit Unified Sensor Driver libraries to read from the DHT sensor.You need to install a couple of libraries for this project: Additionally, many of these modules already come with an internal pull up resistor, so you don’t need to add one to the circuit.

The pins should be labeled so that you know how to wire them. Note: if you’re using a module with a DHT sensor, it normally comes with only three pins. (This schematic uses the ESP32 DEVKIT V1 module version with 36 GPIOs – if you’re using another model, please check the pinout for the board you’re using.) Take a look at the library documentation on its GitHub page.

“Simple template processing engine to handle templates”.

“When you send the response, you are immediately ready to handle other connections while the server is taking care of sending the response in the background”.

“Handle more than one connection at the same time”.

Building an asynchronous web server has several advantages as mentioned in the library GitHub page, such as: To build the web server we’ll use the ESPAsyncWebServer library that provides an easy way to build an asynchronous web server. You can watch the video tutorial or keep reading this page for the written instructions.
