Distance sensor

Accurate distance sensor


Total newbie with regards to robotos, but fascinated by the topic. I'm working on a hobby project, which is not really a robot, but I need "robot" components. I'm searching for an accurate distance sensor, capable of sensing distance between 0 and 5 cm (could also between 1 and 6, for instance), with accuracy around 0,1mm. I see some of you are using Sharp distance sensor GP2Y0A02YK0F and similar, but I have not found what is the accuracy of those sensors, so I don't know if it would be appropriate.

New cheap sonsor for the Start Here robot?

The Sharp IR sensor that is used in the present "start here" is no longer being produced.

We need to find a replacement, and all ideas welcome.

Conditions: It must be a cheap distance sensor that can be purchased "in the shops".

Cheap, and commonly available.

I am sad to say that I do not get much time to build any robots these days.. However, every now & then I get a few moments in my workshop.

Thanks to OddBot I got myself some phototransistors a while back, and now I had some time to play. I was thinking of making 2 robots send little signals to each other via a light beam.

Unfortunatly it's winter time in Denmark, and so I had to work under indoor light bulbs. And as you may know; Working with pulsating light under a such can be a pain!

Update: I am tired of it being named "FritsLDR", I cannot post to people "Try using FritsLDR", it is just too self centered. And I would just love to see some more … Read more
