VL53L1X People Counting range status
Dear,What are the best practices for the people counting algorithm regarding range status? I often get status 2, so I lowered the signal threshold to 400. This reduced it, but did not solve it completely. What status codes should I allow, and which o...
What sensor or combination of sensors would provide the best accuracy in a range of 1mm - 1100mm?
I have read the data sheets for the VL53L0X, VL53L4CD and VL53L1CX ToF senors. I am unsure which one would be the most accurate as the datasheets present the accuracy data at different conditions.Ideally the sensor would be accurate over 1mm - 1100mm...
Resolved! VL53L1X problem with write value to register
Hello, I solve a problem with writing the value to the register of sensor VL53L1X. It is the main purpose, why the sensor doesn´t read distance because the init state is invalid. For example, I tried to write the value 0x2 to the register 0x30 on the...
Resolved! Finding the VL53L1X XTALK calibration distance
I am trying to perform the XTALK calibration for my system that includes a coverglass on top of the sensor. I am not exactly sure what the point of calibration should be. I've read in the forum: "When doing crosstalk calibration you need to find a ta...
Timing budget not kept in VL53L1X
I am trying to get consecutive measurements from the VL53L1X sensor but the timing budget is only kept on the first measurement with the below codeVL53L1X_BootState(dev, &sensorState); VL53L1X_SensorInit(dev); VL53L1X_SetDistanceMode(dev, 2); VL53L1X...
VL53L1X range status 4 on long range
I'm trying to measure distance in a very dark environment. I'm using long-range distance mode. Suddenly, the sensor started sending error 4. What can cause this and how to fix it?Fixed, caused by an issue in the code.
Industry standards to which the VL53L5CX was designed
Hi TeamI want to know the Industry standards to which the VL53L5CX was designed. If you have relevant information, can you share it with me? It is important for me. Thank you!
How does VL6180 do temperature compensation if end product application is an outdoor？
Thank you so much for seeing my question!We are developing a product and intend to use this sensor. Since the end product is used outdoors in Europe, we did some simulation experiments, but found that when the ambient temperature drops from 20 degree...
