Need your help to setup InterfaceKit 1018 with SHARP 0A41SK

Postby rongxike » Mon Sep 01, 2014 3:08 am

Hi everyone,

I'm able to connect the 1018 with the IR Sharp but the device cannot detect the small resolution of mm

Ex: i have 20 pcs of card (thickness is 4mm). so I have 80mm is the height. I put the IR on top at 100mm away from the cards. If I remove 1 card the distance will be 104mm, 2 cards will be 108mm... and so on...

But the result is totally failed. How can I change the formula to make it work perfectly?

Thanks,
Miller

At a distance of 10cm, the 0A41SK is only accurate within 4-5cm. You can increase accuracy by reducing the distance, but I doubt any IR or ultrasonic distance sensor will be able to achieve millimeter accuracy. You may want to look into laser range finders or time-of-flight cameras.
