How difficult is it to re-purpose some thing like this Amazon.com ? This is cheaper, more accurate, and longer range than the other ones I've been seeing for just the sensor.
How much documentation have you found for the device?

Attached is the technical data. Found in its user manual.

That doesn't even name the active device.

Sorry I took a screen clip of the data. Here is the full manual it the clip was taken on page 8.
What do you want it to do?

I'm going to attach it above on a bride pointing towards the river below. There will be a floating thing on top of the water to reflect the beam to get an accurate measurement of the river height. I'm also going to add a GSM shield give updates over cellular.
I'm going to guess you want to connect the laser distance sensor to an Arduino, in which case you'll have to hack the sensor, or find someone who has already done so. That could be quite difficult.

Oh ok. Thank you
Does this thing have any computer interface at all? I don't see anything mentioned in the document you link to. If not, it's going to be really hard to read the data with an Arduino or other microcontroller.

Dang ok, thank you for your help. Could I use something like this?
That looks like a pretty good price for the specifications, especially if they can really get down to that precision.
The biggest problem I see with measurement devices like this is knowing which distance you're actually measuring - in other words, where exactly you have your sensor pointed at.
The banggood sensor looks OK, but it 3.3V input/output only.
Don't try to interface it to a 5V Arduino without using level shifters, or you will destroy it.
