Re: Bannner IR sensor Measures Ball Exit Velocity
Thanks. We are playing around with this as well. The IR sensor is listed as "diffuse" and the visual red sensor is listed as "retro-reflective", but the wavelengths aren't much different between the 2 sensors while the range is significantly different, so I wasn't sure if there was some difference in design that would make them behave differently.
I wasn't sure if the detection spectrum was sufficiently different that it would react better to a specific retro-reflector target while ignoring a different diffuse target (the ball) by tuning the sensitivity.
