Long Distance Range Finder.

Garreth
Hi Guys,

What are my options for long distance range finders on a Mini2440 (or
similar)?

I have found many solutions (Ultrasonic) for upto ~10m but what about upto
maybe 100m?

Could a range finder be used for collision detection?

Thanks.

Hi Garreth

Typically they use laser for long range. Try a more appropriate forum.

Hi Sean,

I was really hoping someone knew of something that worked with a mini2440
"out the box". 
There is a lot about short range out there.

Thanks, I'll go hit up Google again.

Garreth

Thanks Paul.

That is a little extreme for my purpose.

I have just been told that I cannot use lasers which changes my plans a
little.

My goal is to work out what obstacles are within range and how far they are
away. 
Sort of a rudimentary collision control system.

The outer range would probably be under 150m which seems to rule out
ultrasonic.

If anyone has any thoughts I'd be interested in discussing ideas. I know
there are some smart thinkers on here.

Thanks,
Garreth
