  • hey everyone, hope anybody can help me with this one: for my project i use 2 sharp sensors, (ranges 100-550 and 20-150) building kind of guiding device/obstacle detector for blind. unfortunately both sensors have the same ‘problem’ i can’t fix. as you can see from the datasheet, the output as a function of distance is parabola - therefore every output voltage may have 2 options for distance. despite the fact i want to use only the range 100-550 (for ex.), the sensor does also react to 0-100 giving different outputs which may be interpreted as other distances leading my blindman to hit the wall or something.. . i’m using the sensors with Arduino, and can’t find a way to handle this double values problem.

    will be very very grateful for solutions or ideas Gary
