IR-RX back
The infrared trigger introduces two new modes of operation to my camera traps:
Mode 1 is a no-hassle bream break mode. Distance is limited to approximately three feet with a single 120 degree SMD IR LED at 30mA. More powerful or more directional-beam diodes will yield a longer beam distance. Aligning this beam is trivial, with an almost 45 degree cone spread from the LED baffle (from a straight line).
Mode 2 is a proximity detector which is somewhat specialized: both the emitter and detector sit side-by-side and if an object approaches within about 1 foot the reflected IR will set off the trigger.
