> Range is 10/40/60cm with accuracy 1/2/3mm (apparently there is some kind of scaling factor). The "accuracy" you mention is really what they call "Range Resolution", which is more a measure of precision than accuracy. The range (as well as this resolution) is determined by the modulation frequency of the device, which I presume is the setting you switch to change modes. > I wonder where such short range measurements with such a low accuracy are useful. Another commenter mentioned autonomous vehicles (small vaccum robot), however I think outside of that use case there's really not much. Honestly for most things at that kind of range, I'd probably prefer to use a PMD camera like the Pico Flexx [1][2]. It's a lot more expensive, but you get a much better range, higher frame rate, and takes full images instead of just a single range in front of whatever it is you're building. Granted the range is 0.1-4m because the modulation frequency is fixed, but for most applications where you want autonomous ranging I can't see this being too much of a problem.
