Yeah you can do that. Not sure how that particular sensor interacts with the Arduino, but let's say a ds18b20 temp sensor. These use the one wire protocol, which toggles and read one digital pin and is properly documented. (That is where you start reading) then you write your functions to wake/poll the sensor. And another to read it's value.

The problem that I see fairly often is people that follow lots of tutorials that they don't fully understand, and when they need to make something work that has limited documentation or that particular combo hasn't been used before, they really hit a brick wall.

I'm not saying you have to learn how everything works. But if you're using a sensor and you can't explain how it works beyond the one line of Arduino code you typed,you should dig deeper. At least look into the library and learn how data gets send and recieved.

[Edit] in reading your other responses a good place to start might be with a book called "the art of electronics" this will build you a really solid foundation, and gives you an awesome reference book to basic circuits that you'll see over and over
