The Arduino ecosystem is so large that there are many libraries for sensors. The Arduino library makes it easy to test your sensor on Arduino board. I will explain how to use the library on Arduino.
Find and download a required library below.
By default, the Arduino IDE searches for libraries in
~/Arduino/libraries at startup. So, move or copy the downloaded library to
~/Arduino/libraries and restart the IDE.
In general, the directory tree looks like this:
If you know the library header, include header using
#include. If not, find the library in Sketch -> Include Library menu.
If you are new to the library, read the docs about it. Another good way to understand the usage is to look at examples. In general, Arduino libraries have own examples. Find the example in File -> Examples menu.
Different sensors use differently, so you should search for this or read the datasheet. Believe God Google...
