I am using the code Jordi released here, and i'm getting about 2 meter peak to peak readings when the sensor is absolutely steel. I expected much better results, the manual says 9 cm resolution. what good is it if the noise is 20 times as much?
I've had similar experiences with the SCP1000. Also note that the SCP1000 supports separate power supplies for analog and digital parts of the sensor (which many people ignore) and therefore depending on your setup, you may not be getting the best out it.
But I think the 9cm resolution they quote is averaged over a long period of time, not just an instantaneous measurement.
