Re: IR/ultrasound sensing angle

The sonar fans out and returns the distance to the closest object in the fan within detection range. The detection fan of the LZ-MaxSonar-EZ1 that came in the KOP is about 4 or 5 feet across when it gets out 4 or 5 feet. Other models have different detection fans, but they all spread out to varying extents.

The IR sensor is more directed. It spreads out a little, but not much. It's affected more by how reflective the target is and the angle the IR beam hits it at (bounce).
