· Re: VL53L0X TOF Distance Sensor Readings Not Accurate. by chaeron on Mon Jan 16, 2017 2:30 pm. The default timing allocation for the sensor is 33ms, so running just less than 40ms overall seems pretty reasonable, given the extra overhead of API calls, and whatever you are doing between calls. You can change the allocation to 20ms, which is the ...
