 Simple short range IR/laser beam break position detector
Hi Trying to get ideas on setting up a short range (500mm max) beam that if interrupted provides a trigger of sorts. The range needed is short but accuracy or "width" of beam should be a mm or so at most. I am hoping to not use a reflector at the "receiving" end of the beam. Is this possible? IOW, a beam generator that would generate a 1mm round beam for 500mm that if broken by an object will provide a trigger. | |
