Well, here is a question for the PIR experts. One of the suggestions for my mailbox surveilence project involved a heated resistor. I'd like to place a piece of tape over the fresnel lense, and place an infared emitter under the tape on one side of lense. My question is; If I understand the PIR operation correctly, it acts something like a comparator. If either of the sensors goes high, the output goes high.
If I place an IR emitter in the 940 nm range, and 13-15mW output, will this damage the PIR by hypersaturating the sensitive sensor? Thanks all.
