Re: IR/ultrasound sensing angle
It depends on the model/make, but as an example I'd say the beam from a Banner QS18VN6LV widens 6mm or so per foot of distance. The beam is about 8mm at 6", 11mm wide at 12", 14mm at 18", etc.
A Sharp GP2Y0A02YK0F beam is about 6mm wide at 12", 12mm wide at 18", etc.
