VL53L0X Field of View
I am building a project using the VL53L0X. This ToF sensor has a 25 degree field of view. When aimed at a flat surface, the returned distance is accurate. However, if the surface is angled, the distance returned is more than the closest point on the object (see pic). Is there a way to narrow the FOV or would using two or three sensors resolve this issue? Thanks!

Re: VL53L0X Field of View
Thank you for providing this specific diagram. That makes it easy to understand your situation.
Multiple VL53L0X (eg. 2-3) would be a good option since this has such a narrow light beam. You will need some extra code for everybody to place nice. Check out this thread for details.

Re: VL53L0X Field of View
Thanks, Mikey! I am going to try three (one centered Adafruit and two generic on either side) and see I can code up a solution that gives me the correct distance. Since the post date of the link you provided, there are several toots on setting a unique address for each sensor on a single SBC. So that part should come together quickly. The code to take three inputs and derive a single accurate distance may be a bit more tricky. :-)
