What is the difference between directed IR transmission and diffused IR transmission?
What will be an ideal response?
A directed IR transmission requires the emitter and the detector to be pointed directly at one another; a diffused IR transmission relies on reflected light that can bounce off walls or other objects. The emitter and detector do not have to be pointed at one another for a diffused IR transmission.
