Hi all, as stated in the title I'm struggling to find some high precision (~0.1mm) short distance (1 - 15cm) sensors. Not sure if I'm searching wrong or such things are not really common. The only one I found so far is this:
but I'm either blind or they don't share what's the accuracy of this thing and I don't understand how can you not include that info for a distance sensor??
Any other recommendations? To give you a bit more context, I am working on a hobby project and I want to measure the distance of a car from the ground to the bumper so ideally, the sensor should be fine for outdoor use (but I can build a case for it as well so not that hard requirement) and ideally it should be fine to measure the distance constantly on a moving car. Also are how would optical sensor (IR like the one above) behave on a wet day? Meaning measuring the distance from a bumper to a wet road? Would it still work, not at all or would give false readings?
