Hey guys,

We have been experimenting with Maxbotix ultrasonic sensors and are a little disappointed by the output we are getting. We are trying to use the analog voltage output and (as verified by a voltmeter) the signal voltage will hold constant for a given distance and proceed to drop some and slowly walk back up to the stable voltage. 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?
