The sensor reacts to an interruption in the beam of infrared light that is transmitted between the transmitter and receiver. When the beam is interrupted by another object, the receiver signals this event by lighting up. The module is equipped with a 3 mm IR LED with an illumination angle of 10°. Beam interruption systems are used e.g. in measuring gates.

Wiring these sensors for Arduino use is really easy.
First up you'll need to power the transmitter. Connect the black wire to ground and the red wire directly to 3.3V or 5V power. It will draw 9mA from 3.3V (lower power) and 20mA from 5V (better range)
Next up you'll want to connect up the receiver. Connect the black wire to ground, the red wire to 3.3V or 5V (whichever logic level you like) and then the white or yellow wire to your digital input.
Note that you do not have to share power supply ground or power between the two, the 'signal' is sent optically.
The receiver is open collector which means that you do need a pull up resistor. Most microcontrollers have the ability to turn on a built in pull up resistor. If you do not, connect a 10K resistor between the white wire of the receiver and the red wire.
On an Arduino, we'll connect the signal (yellow/white) pin to Digital #4
