Waitaminute...we need a tech timeout.

We emit far-IR radiation, but this sensor is looking for near-IR light. Very
different things, very far apart on the spectrum. A remote control sensor
cannot ever detect IR radiation. Otherwise PIR motion sensors and IR
receivers would be the same, and they're not.
