Hi everybody, I need some help with the ping sensor. this sensor sends signals in a certain angle range, so it will detect anything in that range. I need to detect only objects that are precisely in front of the sensor and not in all the range.
I was thinking about wrapping around the sensor a cylinder. The cylinder will have to be made of soundproof material so the waves will not bounce on the sides. Anybody has some advices on how to do it? Did someone already solved the problem? Are there any kits already available?
Thanking you all in advance,
wallino
