VL53L0X Field of View

Post by pixelpop »

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!

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.

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. :-)
