While I could use the data sheet to apply the sensor to this task, I've been doing this for 40 some years now and have the experience to do it. It sounds like you are new to electronics, in which case your question is likely too low level. What does the IR sensor need to detect? How far away is whatever it needs to detect? Being lazy (and knowing how much trouble it is to use bare IR sensors 
) the first thing I did was search ebay for "ir sensor arduino" which comes up with this example:
which looks to use the same sensor (or one like it) that you are considering and has the necessary interface logic and parts to get it to interface to an arduino. Being ebay, it likely has no documentation, but there are a number of sites that google will find with connection instructions and likely arduino code for ir sensors. Until you get experience you are likely better off buying modules (ebay and the like have almost anything you could want ) and perhaps looking them over to see how they have solved the problem to learn how you could do it. You will need to get good at searching google to find documentation (sometimes only data sheets and tracing connections back from there) to figure out how to use them though.
