IR sensors connections

Hello guys....just beginning to work with arduino and am learning many things. Please explain me how to  control the output of the IR sensors. How can i find out the Vcc, Ground and output. Please also explain these terms to me. I have uploaded a pic. And i am using 5 sensors so how can i create a common power source for all through the arduino board? thankyou guys.IR sensors TX and RX

it has been decided that the receivers are TSOP17xx. Where the xx stands for the frequency that the receiver will recognize at the longest distance. There are 4 options; 30kHz, 36kHz, 38kHz, and 50kHz. You will need to find out what frequency your receivers will respond to first.

That will require you to blink an IR LED at the 4 different freqencies and try to get the receiver as far away as possible from the LED. Until you answer that question, you are kinda, well, stuck. :)
