Problem with TOF050C-VL6180X time-of-flight (TOF) sensors

Jwinns · ‎2025-04-15

Maybe someone can help me. I bought five TOF050C-VL6180X time-of-flight (TOF) sensors, which also work with the Adafruit_VL6180X library, but they behave completely differently:

Two:
At a distance of 30 mm, the script shows: 0 mm
At a distance of less than 30 mm, the script shows: VL6180X_ERROR_RAWUFLOW "Raw reading underflow"

One:
At a distance of 20 mm, the script shows: 0 mm
At a distance of less than 20 mm, the script shows: VL6180X_ERROR_RAWUFLOW "Raw reading underflow"

The other two: The script shows approximately the correct distance, and you can also Get unlimited close without triggering the "raw reading underflow."

However, for my project, I need four sensors that are calibrated approximately the same. What can I do? Does anyone have any ideas?
