flightsense传感器的准确性怎么样?

嗨,大家好 !
由于扩展板X-Nucleo-6180XA1和STM32F401RE上的卫星,我正在研究flightsense传感器。我有一些问题:
我想知道传感器的准确性吗?
此外,我想用它来确定传感器和目标之间的距离。
我已经实现了示例代码并根据我的情况进行了调整。我想以至少0.5mm的精度测量距离。但传感器仅通过I²C总线以毫米为单位发送结果。
是否有可能有更准确的衡量标准?
最后,由于SPL库而不是HAL库,我在STM32F103上工作。我试图实现代码但不成功...
你有这个库的例子吗?
提前致谢,
最好的祝福,
弗洛里安

Hi everyone !
I'm working on the flightsense sensor thanks to the expansion  board X-Nucleo-6180XA1 and a satellite on a STM32F401RE. And I have some questions :
I would like to know the accuracy of the sensor ?
Also, I want to use it to determine a distance between the sensor and a target.
I have implemented the example code and adapted it to my situation. I would like to measure the distance with at least 0.5mm of precision. But the sensor send only the result in millimeter by the I²C bus .
Is it possible to have a more accurate measure ?
Finally, I work on STM32F103 thanks to the SPL library and not with the HAL library. I tried to implement a code but unsuccessful ...
Do you have an example with this library ?
Thanks in advance,
Best regards,
Florian

你好Florian,
该设备不能支持真正的亚毫米精度。您需要VL53L0X,并且至少需要200ms的时序预算才能使器件收敛到如此高的精度。
此VL53L0X仅通过API进行控制,并使用HAL进行I2C管理,使用STM32F401的代码示例。

Hello Florian,
This device cannot support a real sub-millimeter accuracy. You need the VL53L0X for that, and at least 200ms of timing budget to let the device converge to such high accuracy.
This VL53L0X is only controlled via an API with example of code for STM32F401 using the HAL for I2C management.

你好多米尼克,
谢谢您的回复 !
我认为VL53L0X不符合我们的标准,因为我们想要测量短距离(最大10厘米)而不是长距离。

Hello Dominique,
Thank you for your reply !
I think that the VL53L0X will not correspond to our criterias because we would like to measure short distance (maximum 10cm) and not long distance.

你好Florian,
实际上,VL53L0X的设计距离比VL6180X更长。但如果你的最小距离是5厘米,它运作良好。
最好的祝福

Hello Florian,
Indeed, the VL53L0X is designed for longer distance than VL6180X. But if your minimum distance is 5cm, it is working well.
