IR sensor from other devices, on arduino

This looks like 3 signals, power (probably 5V), ground, and a data output. My guess is that it's a logic-level IR detector like a PNA4602. It should be possible to use this with an Arduino.

For an example of how to use logic-level detectors with an Arduino, and how to learn and re-create IR signals you can look at our sample code for the Gadget Shield.
