Greetings!When I measure objects closer than 10 mm from the VL53L4CD, the result deviates significantly from what was expected, and the result also varies significantly depending on the texture and gloss of the object.Is it possible to configure the ...

I am a beginner in this field. Can anyone help me?I am testing Adafruit VL53L4CD and Arduino Nano with Atmel ATmega328P 16 MHz processor.Only 10 cm. wire is connecting the Adafruit board and the Nano board.I have an issue with status code using ST VL...

Greetings.how to detect that the VL6180 sensor beam is totally blocked (the sensor directly touches an object)?When an object touches and blocks the VL6180 sensor, the sensor returns distances of 255 mm and typically the error message: ECE (Early con...

Greetings John. I have solved the problem of detection of blockage of VL53L4CD sensor close using 0,65 mm air gap and 0,35 mm 9H photo cover glass (1 mm distance in total). The minimum detection distance is 24 mm. I have developed a program for objec...

Thank you John.I will look into the VL53L4CX. In the manual it says: ST histogram algorithms ensure cover glass crosstalk immunity beyond 80 cm and dynamic smudge compensation for targets below 80 cm. It's exactly what I need.Anyway I have been worki...

Hello Anne.I followed your advice, and tested time budget = 200 milliseconds and cover-glass. Unfortunately it didn't give better results. The use of cover glass gave slightly worse results. See uploaded graph (picture) with comparisons (VL53L4CD mea...

Thank you john for the clarification.To help others get started quickly, I've uploaded an Arduino sketch with all the range return statuses.Regards Joergen

Thank you John.I will try the solution with protective glass and experiment with ECE. In all circumstances, it is necessary to protect the sensor from dust and dirt in order to ensure stable operation in the environment in which the sensor is to be u...
