The easiest way to install the library is via the Arduino IDE library manager. In order to interact with the sensor using a higher level API that abstracts the lower level details of the one-wire communication, we will use this Arduino library. It works with a supply voltage in the range of 3. The interface with the DHT22 is quite simple since it uses a single wire protocol, meaning we just need to connect it to a single GPIO of our microcontroller. One to display the temperature and the other to display the humidity.You can consult the datasheet here. We set the font size for the heading h2paragraph p and the units.

There are also two icons to style our page. There is a paragraph to display the temperature and another to display the humidity. As you can see in the above figure, the web page shows one heading and two paragraphs. To get the temperature in Fahrenheit degrees, comment the temperature in Celsius and uncomment the temperature in Fahrenheit, so that you have the following. To convert a float to a string, use the String function. The readings are returned as string type. We also have a condition that returns two dashes - in case the sensor fails to get the readings. Getting sensor readings is as simple as using the readTemperature and readHumidity methods on the dht object. 098 – sospensione colloqui con i genitori. Insert your network credentials in the following variables, so that the ESP32 can connect to your local network. Keep reading if you want to learn more or jump to the Demonstration section to see the final result.įirst, import the required libraries. Follow the next steps to install that library. Follow the next steps to install the library. The pins should be labeled so that you know how to wire them. You can use the preceding links or go directly to MakerAdvisor. Take a look at the library documentation on its GitHub page. Building an asynchronous web server has several advantages as mentioned in the library GitHub page, such as.
