Re: Reducing noise on the MaxBotix ultrasonics?

There was a team that posted their solution in previous years... I don't have link saved... but it boils down to, make x samples, sort the values, throw out the the a few of the largest, and a few of smallest, then average.

example, take 10 samples, throw top 2 and bottom 2 out, average over the remaining 6.

In the past these sensors have proven pretty good when used this way. The problem is when they are off, they are way off, so even a simple average data gets skewed.
