Recently, I started a post about drift in the static level measurement using the VL53L4CX. I received some directions to continue the investigation, which I followed. I tested the performance by toggling the XSHUT pin as suggested, but it didn’t work. So, I proceeded with testing the drift using the ESP's temperature readings and found some interesting results.
Using a fully black plastic bucket with around 10 mm of water, I observed that the drift occurred at two specific times: 8 AM and 6 PM. These times coincide with when the air conditioner turns on and off at the company where I work.
The drift is perfectly parallel to the ESP’s temperature variation.
I believe the sensor isn’t operating within the correct range during these temperature fluctuations, or it’s not applying the proper correction for them.
I’d like to ask: Is there any way to make the correction more accurate, or even fully disable the temperature correction so I can calibrate it locally?
I'm creating this new post because I accidentally marked the first answer as the solution incorrectly.
