I installed a library correctly, yet it is not recognized in the Arduino program

Hi:

I've been trying to use this library to use a sensor in my arduino project. I know I installed it correctly because it shows up in the libraries menu:

Yet when I try to add it, it shows up as normal text, and does not recognize any of the library's commands whenever I try to compile:

I already tried everything, and nothing works. Can anyone help me with it, please?

Please post your sketch USING CODE TAGS(</> button on the toolbar).

That's because the library doesn't have a keywords.txt file, which is necessary for keywords highlighting in the IDE but doesn't have any effect on the functionality of the library.
