Hello - We are using VL53L1X to range a relatively short distance - from 0 to ~400mm. We have a fixed target, which only moves in and out toward the sensor. We want to know this target's position accurately, and update it frequently. We have the sensor in the short distance mode, we calibrate a position, and we think we have a fundamental understanding of how the sensor is seeing the target. All seems to work fairly well. BUT, every so often, in an unpredictable way, without any external or environmental stimulus (that we can tell), it seems as the sensor reports a 'blip', whereby it reads a different value and then recovers to an original value. This happens in less than 1-5 to 2 seconds. There may be cases where it does not recover, but we can see an event we trigger on movement of the target, and then an inverse event.
We are letting the sensor range for DAYS or even WEEKS without stoping the ranging or reseting the sensor in any way. Is this appropriate? Is there a potential cause of above or expected behavior of the sensor we should know about in this type of application?
Any input/feedback would be appreciated!
Thanks
Doug
