Differences between VL53L1CB and VL53L3CX ? Which one would be better fit for a people counting solution?

AMart.9 · ‎2020-09-24

Hi there,

We are from a Spanish startup who is building People Counter solutions based at the moment on the VL53L1X. We want to move to a multi-target solution. After assisting to one of your webinars, we are aiming to migrate to either the VL53L3CX or the VL53L1(in some places we find it like that shortcut and in some as VL53L1CB).

Going through both documentations it has been quite difficult to distinguish which one would be better for our case. Both give ranging distance per object detected and min and max distances where object is located. As differences we find that the vl53l3cx also gives the signal rate per object detected while the vl53l1 doesn't specify that.

Another difference that we see is that the VL53L1 is able to have a multi-zone resolution. How is it different than when we manually define different ROIs on the VL53L1X?

Thanks a lot,

Alberto.

people counting requires different zones. And differnet zones requires a lens. Only the VL53L1 series has a lens. So unless you use two chips to get your zones you have to pick the VL53L1X or L1CB. L1X is a touch easier and will do what you wnat. (The code is available on ST.com)
