Hi,
I am looking for a small, distance sensor that can go up to 150 meters, or 250 if possible, to be used in daylight environment. Is it even possible? Accuracy is not a concern as long as it is maybe under 2 meters margin.
I'd hope to avoid taking the one off a golf cart sensor for example, since I would have no way of relaying the distance measured to the chip without somehow hacking it.

The only 'distance' sensor I am aware of with that range is an IR but it is stationary.
Check this link and see if it helps: Pew Pew! An Arduino Based Laser Rangefinder | Hackaday
Wouldn't IR be unusable in broad daylight?
Will an ultrasonic sensor go up to that range. Then it would be a viable option
Looks promising, however it appears to have a too high wattage so im concerned about its safety, I would not want to push further than class 2 lasers
They used pulsed IR light and look for a return echo with the same pulse length. I have seen them work over a two block distance in bright sunlight in mid summer.

Not if the receiver is enclosed in a cone.
