Imaging (sensors)

VL53L1 TOF sensor: We use the VL53L1CBV0FY/1 sensor. 1. What is the cleaning protocol if dust gets on to the sensor? 2. Is this sensor available with dark protective film to enable easy detection and removal of the same during use?

We have sensors failing because of what looks like dust or debris that is getting on the sensor. Also, often it is difficult to detect and remove the Kapton tape covering the sensors. The tests we run pass even though the film has not been removed so...

Visual Code is not recognizing "windows.h" from "vl53l0x_platform.c" of VL53L0X's API. How should I proceed about this?

Getting fixed value from Lidar (tfmini)

Hi,I am planning to use VL53L1X ULD API for calibration functionality. Host system is Raspberry PI and I got source code of VL53L1X ULD and Example Application from https://my.st.com/content/my_st_com/en/products/embedded-software/imaging-software/st...

Multiple VL53L1X sensors with 5x16 RoI arduino programming

Hello, I hope someone can help me with this.I have 3 VL53l1x and i have connected and programmed all of the 3 sensors to a arduino nano and I am receiving data from all three at the same time.I tried to perform 5x16 RoI for all three VL53L1X sensors ...

Inconsistent behaviour of VL53L1X ToF Sensors

Hi, We have been testing the VL53L1X for a while. The primary intend is to measure liquid level. Liquid can be water, coffee, windshield washer fluid, etc. We are seeing some issues that we cannot seem to figure out. Hoping for any insights.Premise.W...

Measurement problem on VL53L3

Hello, I use a VL53L3cx sensor and API STSW-IMG015. I am having two problems. The first is that in the interruption mode, the VL53L3cx stops sending the interruption after 20 received measurements, speed i2c 400khz. The second problem is that the se...

VL53L1X ULD short range behaviour when target is located outside of measurement range

We are using the VL53L1X sensor with the ULD API in one of our products. During final evaluation we encountered situations where the sensor delivers wrong measurement values with status OK. In the attachment you will find the documentation of measure...

Timing configuration difference between VL53L1X ULD and API

We are currently investigating an issue with corrupted measurement results of an VL53L1X using the ULD API in short range mode. The sensor delivers results with status ok but completelely wrong ranging values at target distances exceeding the range o...
