Reading analog value from IR Receiver

Hi I currently bought a pair of these to make a IR barrier and I want to detect when it is broken.

http://www.ebay.ie/itm/5mm-IR-LED-Pair-Infrared-TX-RX-transmitter-receiver-Diode-x-2-Pair-/261666210619?

The problem is I cannot get a value from the IR Receiver has anyone any idea on how to hook this up? Here are the specs from the Ebay page.

Specifications:

Transmitter (Tx):
Power: 0.1W.
Maximum Current (Approx): 0.5mA.
Launch Angle (Approx): 45 Deg.
Wavelength: 940nm.
Typical forward voltage drop: 1.1V.
Diameter: 5mm.

Reciever (Rx):
Power: 0.15W.
Maximum Current (Approx): 30mA.
Receiving Angle (Approx): 45 Deg.
Wavelength: 940nm.
Typical forward voltage drop: 1.2V.
Diameter: 5mm.

Kind regards,
Frank.

Not surprising these are just the raw IR LED and IR diode, you need an amplifier of some sorts. Even then the distance will be limited to a few inches.

This project shows you how to hook up such a system:-
