Can someone point me at decent reading about infared? I am looking at a
project involving infared detection, sunlight, and people. Suffice it to
say this is someone else's idea about which I am instructed not to be
specific.
In this application, I ideally want to sense people with complete
sunlight rejection using infared. The 2 standard techniques - Emitter
Pulsing, and movement detection as used in home alarm PIR detectors are
unsuitable for various reasons. False positives are basically
unavoidable, and I can cope with that. I want to minimize it, however.
I don't want false negatives, however.
Let me be more clear: I am not worried about the orb of the sun creating
a false positive. I AM worried about not picking up something (i.e. a
false negative) at 30 degrees right or left of it.
