I'd like to start a new project that will allow me to measure rooms using some sort of laser or ptr or ultrasonic modules but i cant find any components (with a very brief search) that measure more than a few feet. I need to be able to do about 70-100ft. any suggestions for component?
Are you good at hacking commercial products? Check one of these laser tape measure devices out!
Or perhaps a microwave rangefinder? Although anything with that kind of range isnt going to be cheap. The kind of sonar units they use in boats have the range but may not be calibrated for above water usage.
You can find lidar guns on ebay in the $2-300 range.
I wonder what technology they use in the eBay $15 "Digital 7x Pocket Golf Range Finder Golf Scope Yards Measure Distance".

I'm no noob to coding but I'm new to the introduction if hardware I have no idea how I would get inputs from this but it would be cool
Probably the same old spit-image rangefinder tech used in Leica cameras.
