Re: Maxbotix Ultrasonic Sensor Help...

This issue becomes more apparent at longer distances, to the point that the sensor readings are very rarely reliable.

We are sequencing the sensors using an interface board to avoid interference and as near as we can tell the setup is fine.

Has anyone else experienced this type of behavior? Any suggestions?

1075 Has been playing with the EZ1 variant of these sensors and experienced the EXACT same behavior... it IS more pronounced at higher distances too
the walking back up to the correct number can take several seconds too
