Interference between ToF sensors (VL53L5CX)

I am wondering how to extend the FOV of the 8x8 tof sensor. I think on mounting two or three VL53L5CX in a horizontal array. However, since all sensors operate at 940nm, I should place them far enough to avoid that the reflection on one is detected b...

Range sigma of VL53L5CX is too low

Hi,I have read the tutorial and document about VL53L5CX. It says that the distance of targets and the range sigma are extracted from histogram by assuming a normal distribution (the distance and range sigma are the mean and standard variance of the d...

Is there any kind of document / application note for VL53L5CX available to guide how to calculate the number of sensors required given the ceiling height and the passage width?

We need to understand the best topology / positioning when considering some different situations, for example:1) passage with of 0.8m with ceiling height of 2,60m2) passage width 1,5m, ceiling height of 2,60m3) passage width of 3m with ceiling height...

Typical issues with VL53L1X, range and status

I am checking signal status also for Big obstacle it showing Distance up to 2.1 meter(210Cm) and status is 0, and for small obstacle showing distance up to 1.2 meter(120 cm) and status is zero, it is not useful in outdoor environment , and it Hangs a...

VL53L5 init stalls at get offset NVM data

I'm implementing the VL53L5CX ultralight driver on an ATSAM4L. The sensor responds correctly when requesting Device ID and Rev. The init function runs without errors (status = 0) through the loading of firmware and restarting the sensor's MCU. But on...

measure target through a tube

I can see from the datasheets (VL53L4CD for example) that the emitter and sensor volume is represented as two cones that start at the sensor face and grow bigger as the distance from the sensor increases.If I am measuring the distance to a target tha...

Resolved! Comparison of features of various ToF Sensors

I'm a little frustrated that there isn't a "Here's ST's Time of Flight sensor offering and which sensors have which features" kind of page. The sensor datasheets themselves also do not give any real comparison data to other (pin compatible) parts.Fro...

Resolved! VL53L4CD Low Power mode power consumption?

Hi,I am trying to find a low power solution for close range (down to 1mm) proximity detection at 1Hz frequency. It seems VL53L4CD can do the job pretty good but I didn't find power consumption details of low power mode in the datasheet.I also found t...
