Distance Measurements


#1

Has anyone found a sensor that is good for measuring distances of 100 ft or so? I have looked and I like the https://www.sparkfun.com/products/14032 but for that price, I want to seek out alternatives first.

Edit: Found it cheaper directly from Garmin https://buy.garmin.com/en-US/US/p/557294/pn/010-01722-00#additional

https://www.seeedstudio.com/ also have some options. But the distance you want will require $$.

The Feature-Page sais Range: 0-40m
I don’t think that there are cheaper solutions for such a long distance.
I just got a small (really small, and about $6 if I remember it right) TOF-distance-sensor but it’s only capable of measuring about 2m in the dark, if it’s in a bright environment it’s more about 1m…
