Hi all,
I am looking for a way to measure small changes in distance within a defined space of 3 Meters. I have been looking at the specs for the HRLV-MaxSonar range of ultrasonic sensors which show that the resolution of these is 1mm. My issue is that with this resolution, my object will have moved outside of the 3 Meter space by the time the change in distance I which to measure has reached 1mm. My question is, is it possible to achieve a greater resolution than 1mm for distance measurement with any other form of sensor or combination of sensors (or indeed another ultrasonic sensor) or possibly increase the resolution of the HRLV-MaxSonar sensors? I would be looking for a resolution of better than 0.1mm over the 3 Meter range. I hope this is clear but please feel free to ask any questions for clarification.
Many Thanks,
Andy.
