Re: Using IR distance sensor at infinity
I know the range of the sensor but don't know the distance to what I am measuring. A reading of 1000 could mean the distance is 1000 (within range) or 2000 (out of range).
My goal is to make a remote vehicle that sends a map back to the controlling NXT. So the vehicle can be operated while unseen.
I did some preliminary testing and there is much more scatter when out of range -it should be enough for the program to decide if it is within range or not. Working out an algorithm will be the fun part.
The sensor seems to be fairly robust as far as different surfaces and angles to surfaces. In my experience, it gives reasonable results unless the surface is shiny (like a mirror).
