sharp 57 2y0a710 Conversion factor

Hi,

Does anyone know the conversion factor for the sharp 57 2y0a710 distance sensor.

Thanks!

there’s the link

I couldn’t find it in the data sheet.

Pages 3 & 5, looks like. I’d go off the inverse graph and fit a line to that. Alternatively, you could make a lookup table.

I tried the slope of the graph on page 5 as the conversion factor, ad it was completely wrong.

Remember, it has to be the inverse of it.

We tried it, it did not work. Thanks!

I assume you’re using these sensors to measure out to the field walls. Do you know if it works well sensing Lexan? We also wanted to use IR sensors but were worried that the beam goes right through clear materials, so we went with ultrasonics instead.
