There is a lens in my system. I came across AN1983 from Renesas on their TOF sensor xtalk calibration. It suggests using IR blocker directly above part of the lens that covers the photon detector in the calibration process. Do you think doing that ...

Thanks for your speedy reply. I read ST app notes and notice the xtalk calibration was done at 140mm. I used 0.97m is because this is where objects are passing underneath the sensor (nominal person's head from VL53L1X mounted on the door beam). Do...

Search for UM2356, Figure 7 has the answer to the XY direction question.

I did the calibration on offset on VL53L1X. Then get the offset value by calling getOffset() which is 1336. Use that in setOffset() in subsequent measurement. xTalk gives 15912. Cal distance used is 0.97m. But normal ranging at 2m is all wrong. Why?

Do you have API driver on VL53L5CX for ESP32?

Can I use V53L5CX to detect the number of people in a small area like 2m x 2m? If so, how many people can I detect? Can I detect 4 people within 2m x 2m? The sensor will be mounted on top of a door entrance.
