Hello, I have been hunting through the previous posts in the group and cannot find the info I was looking for, can anyone help? I am looking for some optical sensors (sharp??) that are able to measure distances. There are several in their range, each set to different distance ranges. Can anyone shed some light on these or point me in the right direction as to where I can find some info on them.... TIA, /andy |

Some of the Sharp sensor are preset to a certain distance, most are not. The GP2D12
for example has an analog output that varies over it's full range of 10 to 80cm. The
GP2D02 does the same reading, but reports back a digital value of the range. Here's a
summary chart off the Acroname site. http://acroname.com/robotics/parts/sharp_guide.pdf > From: "thor69uk <>" <> > Date: 2003/02/24 Mon AM 11:49:23 EST > To: > Subject: [BasicX] Optical distance sensors... [Non-text portions of this message have been removed] |

One is for a Sharp GP2D12, which has a range of 80 cm, and the other is for a GP2Y0A02YK, which has a range of 150 cm: http://www.basicx.com/Products/BX-24/bx-24appnotes.htm Both sensors generate an analog voltage that is a nonlinear function of range. The two app notes include source code that transforms voltage to distance. -- Frank Manning -- NetMedia, Inc. |
