what would be the best method for human-filtering the result. Erik Malund said:
i do not see how you can do that with a row of LEDs If they are significantly closer together than the minimum width of a "normal" human body then, if only 1 beam is broken, you know that it can't be a "normal" human body - don't you?! You would also need to time the duration of the break - to distinguish something wide enough for a human, but too short, passing through the beams... |
