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...
Hello again!I've been trying to measure water level using the VL53L1 sensor and reading forum posts on it, and I've gathered that RefSPAD calibration isn't really recommended anymore.From my research on the topic, I know that water reflects only 2% o...
Hello,For the vd55g0, you provide a kernel driver and device tree as source here: https://www.st.com/en/embedded-software/stsw-img505.htmlYou also provide a libcamera integration stack (STSW-IMG505_LCAM), but this is closed source, and only the libca...
I bought a STEVAL-55G0MBI1, which is the VD55G0 S-Board eval kit. Trying to output the image to my PC, nothing is coming out. What could be the issue with my setup?
Hi, when using the VL53L1X, it is suggested to check for the range status and 0(zero) is considered the desired range status. Now, as I understand it, the range status 2(two) is dependent on the signal threshold. By default, the signal threshold is s...
