Library Installation
Note: This example assumes you are using the latest version of the Arduino IDE on your desktop. If this is your first time using Arduino, please review our tutorial on installing the Arduino IDE. If you have not previously installed an Arduino library, please check out our installation guide.
We’ve written an Arduino library to make reading the RHT03 a breeze. You will need to manually install the RHT03 Arduino library from the GitHub repository by downloading a *.zip. Once downloaded, click Sketch > Include Library > Add .ZIP Library... to have the Arduino IDE unzip the library into it's respective folder.
