A quick google didnt exactly pull up much about your sensor so i dont really know what youre working with.
If its a sensor with built in demodulation and what not there should be 3 pins. power, gnd, and signal out which is probably active low.
I am using a Vishay TSOP11 series ir sensor for my project http://www.rentron.com/Files/TSOP11xx.pdf
In my case, pin 1 is ground, 2 is +5v and 3 for signal direct to arduino.
You dont REALLY need the cap or resistor, but you should have them anyway.
I can also put you onto a library for the arduino to read the ir sensor if you need it.
hope some of that helps!
