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...
Hi,I have an X-NUCLEO-53L1A2 and a NODE_F401RE.The VL53L1.exe GUI is unstable and frequently freezes, but I could at least perform most of my experimental measurements (including MultiZone Ranging 4x4).However, when using MultiZone 10x10 Ranging, the...
We have two VL53L1X sensors side by side. Both have gilizmo cover glass and are placed 140mm from a 8.5x11 sheet of mat grey paper. Running the calibrate offset function returns 2mm for sensor one and 6mm for sensor two. Following this the Xtalk cali...
An anonymous customer was trying to get the best possible range accuracy with a VL53L5 sensor. His temperature range was from 25degrees C to 50 degrees. This was his plot with no temp cal. After calibrating between the ranges he got: These plots ...
Dear forum,I try to understand the bin shape of the VL53L8CX / CH sensor calibration buffer while evaluating different sensor cover and their influence on ranging. Using the example8 file from the ULD driver the shape looks more or less always the sa...
I am currently working with the VL6180X proximity sensor and would like to inquire about its long-term performance characteristics: 1. What is the expected Light/Luminous Depreciation time frame for the VL6180X's VCSEL source? Could you ...
I’m using a VL53L5CXV0DH/1 sensor in my current setup (see pictures). The goal is to detect a ball rolling between the sensor and the background. The red box is about 12cm apart.The settings is 4x4 for speed, i also noticed that 60 is not the highest...
I need to calibrate a VL53L4CX and have been reading UM2923. The functions described do not seem to bear any obvious relationship to the functions in the STM32Cube middleware which was generated for my project, which I find confusing. I it is not cle...
Hi everyone,I know there are 25 and 35 degree detection angles of VL53L3. I am aware that this situation is a mechanical situation. But I want to make a timing gate and find people's speeds. We have submitted our product to reliability and validity t...
