All you need is an IR LED and and IR sensor with a divider between them. Anything that passes in from of the device increases the signal at the receiver (sensor).

The IR LED sends out a beam of IR light. When there's nothing in front of the sensor, nothing happens. But when something goes in front, the IR light reflects off the object and is detected by the IR detector.

The IR receiver is unidirectional... In other words. It would only work in the direction it's pointed.
