TF-mini lidar distance drops over time

Products & Technology Grove
#1

Hi,



I uploaded the following example: wikistudios(I can’t post links…)/Grove-TF_Mini_LiDAR/

Everything seems to work.

However, the distance keeps decreasing over time.

I guess there is a PLL that isn’t locked…

Is this sensor damaged, or how can I solve this?

It even goes under 35cm after a couple of minutes…

Hi,



Can you check with the the connecting wire , the Maximum operating range at 10% reflectivity of TF-min Lidar is 5m which is 500 cm, so this might be issues with the hardware of software (code).
