Hi ST,Using the vl53l1x in our devices we are finding some cases of unexplained sensor distance changes. Large changes. We use the sensor in a contained/controlled environment. A bin -- the sensor is used to measure distance to items contained in t...
The device does not output the data in a sudden. And it has no effect to press the RESET button. When I try to re-flash the board, the available memory of the flash only remains 8KB. Even the total memory is only shown as 32KB on PC, much less than t...
Hi, We have a board featuring 5 VL6180X sensors and I noticed some oddities regarding the initial offset and scale in the latest production run:Some sensors are unable to measure any distance below 15mmThe ranging linearity between different sensors ...
Hi!I've since given up on utilizing VL53L1X for liquid level measurement. @John E KVAM had previously reccomended me to use instead the VL53L4CD sensor for this sort of application (small recipients with water), and I plan to ship it next week. But I...
Hello ST team.I am operating the VL53L1CB sensor with zephyrRTOS, I reach distances to four meters without problems, in addition to measure distance above them (eight meters top in ideal conditions), all this in ROI.I am working with the manual UM213...
Hello, I'm currently working on a project with a VL53L8X sensor.When I installed this product on the ceiling, the data of adults passing by is well observed, but the data of children passing by is not. I understand that this is a physical limitation ...
I have 5 VL53L8CX on the same I2C bus.I need to set the LPn pin HIGH of the sensor I want to change address.But the problem is that I can also change the address when LPn pin is low as well.Also I also don't know how to scan I2C addresses in only one...
I am trying to use Satel VL53L8 Cx over Arduino due . The library I am using is stm32duino VL53l8cx but I never get any result .Connections were as per the expamples but it did not work.Is there a library I can use for this . I have earlier used VL53...
I hope someone can help me with the accuracy of my VL53L1 sensor. I can’t get the sensor working accurately above 40cm. I am working on a hobby project and want to use the sensor to avoid obstacles. The board I use is not an VL53L1-SATEL. It’s from a...
I am looking into the VL53L4CD TOF sensor but find the specifications on distance accuracy at 10 cm (or perhaps in range 5 - 20 cm) to be murky at best. I need to be able to determine distance to object with accuracy of 0.02 mm (0.001 inches) at thi...
